Subject: 2007a and Mac 10.5 Leopard

From: Jeff

Date: 22 Mar, 2007 19:35:05

Message: 1 of 49

I searched the newsgroup and google for any information on the
compatibility of MatLab 2007a and the upcoming MacOSX 10.5 (Leopard).


Has anyone run 2007a on a developer build of 10.5? My office is
looking to upgrade hardware (intel macs) and this compatibility is a
factor in the purchasing schedule (buy now or buy after 10.5 comes
out).

Thanks!

Hi Jeff,

R2007a already runs natively on all Intel Macs with Mac OS X 10.4, so
why is this decision based on whether MATLAB works on Leopard?

The MathWorks works closely with Apple to ensure that our current
releases work with significant future Mac OS updates, such as Leopard.

However, Leopard pre-release "seeds" require non-disclosure agreements,
so an individual could be violating their NDA if they share information
regarding pre-release seeds.

If you'd like to know whether we test or "pre-qualify" our products on
Apple seeds internally, we have a process for doing this, but it is not
the same as formal qualification, which requires the final Leopard release.

So, the best guidance I can offer is, things are looking good with the
current Leopard seed. However, if you read the Mac rumor web sites,
many of these web sites are indicating that Apple isn't finished yet
with Leopard development and has more surprises for developers and
users; if they're right, our situation with regard to compatibility
could change, and any information you might get now would become invalid
by the time it ships.

So, your best bet is to not condition MATLAB or Intel Mac purchases on
Leopard, or information regarding MATLAB compatibility, until after
Leopard has shipped.

Brian -

Any updates on how Matlab behaves with the final Leopard seeds?

I'm hoping to be able to upgrade next week and keep on truckin'.

Hi Jerrod,

There should be official information on www.mathworks.com regarding
compatibility and any known issues once Leopard is available, or shortly
thereafter.

I am having problems with the installer from 2007b and Leopard. The

Hi John,

Do you have a PowerPC or Intel-based Mac? Is there a mac or maci folder
in the bin folder? What happens when you click the shortcut? You might
be better off contacting support.

This particular machine is a PowerPC based machine that I am using as a test
machine for compatibility before upgrading other machines to Leopard.

I downloaded the MATLAB installer directly from the website.

There is no mac or maci folder in the bin folder - looks like the installer isn't
creating it.

Is Leopard officially supported, or are they going to laugh at me if I call tech
support? :)

I realize that a pre-installed version of MATLAB on an upgraded machine
might still work - I was specifically testing the installer.

Thanks for any advice,

JAW

Leopard is supported, see:

< http://www.mathworks.com/support/sysreq/current_release/macintosh.html >

I think your issue may be with the installer not installing, I don't
think it's related to Leopard. I would check your download
(re-downloading "Mac (PowerPC)") and your license file.

OK Brian - thanks for the link! Nice to see support so quickly after release.
We in the Mac community appreciate it. I will probably not troubleshoot the
installer issue unless I see it on multiple machines - I will try from the disks
at some point too.

Thanks again,

Hi Brian.

I upgraded my iMac (intel, 2.8 GHz, 4GB RAM) from Tiger to
Leopard and the Matlab interface (Matlab ver. 2007b) got
much slower. In particular when scrolling in Editor the
response was so slow that I really couldn't work.
Reinstalling X11 and Matlab didn't improve things.

Am I missing something there? Is there something I
should/shouldn't have done?

Thanks in advance,
Viton

I see the same behaviour on a PPC Dual G5 (with 2 Gb memory). It ain't so
slow that I can't work, but it's slow enough to be majorly annoying, to the
point that you start issuing commands multiple times since the system
appears unresponsive...

Bench numbers do not seem different from what they were, so my initial
guess would be that it has something to do with the java interface. Hope it
gets sorted out though...

Hi,

Does turning off the MATLAB Preferences -> Editor -> Code Folding
"Function Code" result in better scrolling performance?

We will investigate this further.

Hi,

This appears to be a performance regression in Java when using the Sun
renderer, which Java on Leopard defaults to using, but Java on Tiger
does not.

If you create a file named java.opts in /Applications/MATLAB_R2007b and
add the following:

  -Dapple.awt.graphics.UseQuartz=true

then you should be able to get back to Tiger's performance. We will
work with Apple on a more permanent solution.

Hi Brian,

thanks for the quick response. Your reputation guys is well deserved :)

The second suggestion (i.e. use the quartz renderer) is indeed the solution,
even with code folding enabled!

(Disabling the code folding alone indeed speeded up scrolling, but not quite
to the desired point.)

Thanks again,
Viton

dear brian,

i have done this and it works fine since then. however, another minor problem
occurs here with leopard on a mac pro and the newest R2007b. i am using
matlab in spaces in a separate window. after hiding (apple-H) or minimizing
(apple-M) matlab and bringing it back, some keys do not work, in particular i
can't use the return key and backspace for deleting, both in the editor and
command window, whereas typing new characters work fine. so i have to quit
matlab using the menu - typing quit in the command window works, but the
return key does not work. now i simply avoid hiding matlab.

all the best, martin

I can replicate this behavior.

However, simply switching focus away from the editor
(whether to another app or, if the editor is undocked, to
the another MATLAB window) restores expected behavior.

AND...MATLAB will randomly move all of its windows to the
primary space when using spaces.

Haven't been able to reliably recreate this problem but I do
know that the editor is in a separate window, the command,
current dir, and history are in one pane in the main window,
along with the workspace in the other pane, and there are
two figure windows open.

the obvious workaround is rearranging spaces so matlab takes
the primary space and everything else moves...

make sure your java.opts file is actually a .opts file - use
"get info" in finder to double check the extension, and then
ensure you put it in the right place. the fix seems to have
worked for everyone else here.

hey...i checked that. here's the update:

it seems that something else is a little quirky on here. it was indeed
a .opts file, no .opts.rtf ...i double checked that. it was running
slow, so i tried deleting the file, rewriting it, so on. that did
nothing, so i rewrote setting it =false. restarted matlab with this,
closed it, rewrote the file with =true. after 2 restarts, it worked.
now it is running fine, i'm not sure if it was rebuilding something or
what, but it seems to be working fine now. i guess it just took matlab
a little while to understand that i reallyb needed it to work. stuff
copies fine now and scrolls great. i feel like matlab is back on my
side! thanks for the help tho.

I figured out that it's starting up in the X11 window. I'm using the 2007a
student version, so the command prompt EDU>> appears after starting up
bin/matlab from an X11 terminal however the terminal doesn't accept
commands. It appears that the matlab desktop does not startup since java is
disabled?? Out of curiosity, I took the java.opts file out of the root directory,
and I created a startup.m file, and disabled the matlab desktop with the
following command: matlab -nojva. This produced the same result as the
java.opts file. Perhaps quartz cannot run the desktop???

Hi Matthew,

Can you provide the exact xterm output when you launch in xterm? Also,
is there output in the Console application when you launch?

If the presence of this file is causing the UI to not show up at all, it
is possible that the format or content of the file is the cause. Check
that the file type is really unformatted ascii text (not RTF format, for
example, as TextEdit would save as), and contains the expected text
spelled and capitalized exactly as follows:

-Dapple.awt.graphics.UseQuartz=true

Use emacs from the command line, Xcode's text editor or some other real
text editor (not TextEdit) to ensure that the file is unformatted ascii
text, and confirm the file's contents.

to another application from MATLAB and then switch back to MATLAB (either

Hi Andrew,

This appears to be a new issue, and I am able to reproduce it on 10.5.1
using both R2007a and R2007b. Are you using 10.5.1 by chance?

I haven't yet had time to track down this issue, and I don't yet have a

Hi.

I have a new Intel-based iMac 2.8GHz with 10.5.2 and (in
both bench.m and my code previously written on XP) seems
much slower than the same or less frequency (also Core 2
Duo) CPU running XP. I am not referring to the well known
GUI issue, but the actual mathematical operations. This is
extremely frustrating and I think it may be be an issue for
all Mac users. I have seen some info in the web, but without
actual answers. Any ideas? What about the the Lapack and
other libraries binaries the right ones for the new
Intel-based Macs? Any reply from any Mathworks people would
be great ...

Many thanks in advance,

Yannis

All,

I am running 2008a on 10.5.2. I had the same poor java
performance, and tried the java.opts solution. When
launching matlab from the startup script provided by the
installation, either from finder or from the dock, there was
no change. However, starting matlab from a terminal using
./bin/matlab did solve the problem.

This seems a pretty serious bug. While I'm griping, I am
constantly annoyed that matlab occupies two spots on my dock
when running (three when you count X11). The first is a
shortcut, the second is the actual process. Is there no way
around this?

Hi,

Please type this at the MATLAB command prompt:

java.lang.System.getProperty('apple.awt.graphics.UseQuartz')

If that returns false, then your java.opts file isn't getting read.

For R2008a, please locate java.opts inside the bin/maci folder.

As for solving the "how many friggin' application dock icons does this
application need?" problem, we realize this is frustrating but were
unable to resolve it in time for R2008a. We're working on that, and
reducing or eliminating the X11 dependency, without losing some of the
modes customers love (see other threads on this newsgroup for customer
pros and cons).

The java.opts fix worked for the scrolling issue, but now I
get some Java error messages in my command window when
Matlab launches:

They appear to be inconsequential, because Matlab seems to

Hi,

This is a known issue with Java (it can be reproduced under the right

Hello Brian,

I have the same problem of slow scrolling and interphase. Upgraded from
MatlabSV 701 to SV74 on a PowerBook G4 and OS 10.5.2.

I tried the java.opts option. When I prompt:
java.lang.System.getProperty('apple.awt.graphics.UseQuartz')
ans =
 
true

Yet scrolling is slow albeit better than before.

When I go to Preferences->Editor/Debugger I cannot find the option you
have suggested in an entry earlier.

Please advice on this issue in particular and more generally if my system is
doom to be slow. Otherwise I'll go back to my old one. Worked just fine.

Many thanks

Hello,

I have R2008a running on 10.5.4. I tried the java.opts approach in bin/maci
but I don't think it's getting read, because I get 'false' when running the
command below. However, this only happens when I use the Desktop "profile"
in the Start MATLAB Settings.app, because if I run it in xterm or Terminal
mode if returns true. What am I doing wrong (I'd like to run it in Desktop

Hi.

I am using Matlab R2008 and Leopard 10.5 and the only way I
can run it in desktop is by creating a short cut and placing
it on the desktop. Any other way, it doesn't launches. I
know it's a boring and crude solution but it's the only one
that has worked for me....

And besides that it won't launch if you double click on a
m-file, it has to be running before opening m-files. Another
issue is that it won't "Run" some m-files that I used with
Matlab r22007a in Windows XP at work....

OK, it's working now. Not sure why though, because I did the same thing a
previous user reported before (changing it to false, restart Matlab, changing
to true), and that's when it started working.

Another difference is that I finished the java.opts file with a new line, but I'm
not sure if it makes a difference...

I've got a slightly different problem with leopard. I installed R2008a on a new
intel macbook pro. It worked fine, but then I installed the system updates that
Apple sent out. X11 no longer runs, so Matlab does not start.

Any guesses?

Strange, I didn't get this problem, but a colleague had it after updating to
10.5.3. Installing the newest version of Xquartz from http://xquartz.macosforge.org solved the problem (beware though, this is
NOT the official Apple released software!)

If you look into the logs (Console.app) you will see that /usr/X11/libexec/x11-exec can't "find the application for org.x.X11" which
appears to be a problem with launchd. Perhaps http://www.macosxhints.com/article.php?story=20080622105055862 can
help, didn't try it out however.

After reading
http://discussions.apple.com/thread.jspa?messageID=7676645 it seems as
if the culprit is the combo-update. People who continuously updated don't
have this problem, others who applied the combo got it...

Hi Abhinav,

Try some of the following diagnostic tips:

- Open Console (Applications -> Utilities) and report what gets output
when you try to start MATLAB.

- Start MATLAB from Terminal (type
/Applications/MATLAB_R2008a/bin/matlab) and report what gets output.

- Confirm that X11 is installed correctly: does Applications ->
Utilities -> X11 launch? Are errors being reported to Console? If you
had applied a Combo Update to Leopard to 10.5.3 or 10.5.4, it may have
stomped on the X11 installation. If that is the case, you will need to
download and install X11 from here:

< http://xquartz.macosforge.org/trac/wiki >

I recommend version 2.1.1, closest to the currently shipping version.

- Check 'java -version' to see that Java is functioning, it should
return the version number; report that.

- Check that you have a bin/maci directory in your MATLAB install. If
you have a bin/mac directory instead, then you have the PowerPC version,
which won't work in full desktop mode on Tiger (10.4) or Leopard (10.5)
on an Intel-based Mac. Reinstall MATLAB (re-download if you previously
downloaded the installer), making sure to install the Mac Intel (maci)
version.

Good luck,

Brian

This is indeed what I had to do. The repair
was simple once I knew where to go. The
combo update apparently caused the problem.

Hi,

I am running r2008a on a new MBP and am getting nearly all of these issues.
Have you all fixed anything in the new release? I have to say that so far I am
seriously disappointed with r2008. The license manager is terrible, the UI is
incredibly slow, startup creates at least 3 unused X11 command windows,
and you cannot dock the Matlab icon unless you want to create your own
custom automator app. I would expect this from Microsoft, but not
Mathworks.

Btw, the java.opts fix for scrolling does not seem work for r2008a, even with
the set to false, restart, set to true, restart approach.

This fact has long been a thorn in my side as well. Practically everything runs slower on MATLAB in OS X compared to Windows. I've done bench.m comparissons on my MacBook Pro under OS X and Windows XP and found that under Windows the scores come back 4-5 times faster than under OS X. I know of several functions where the implementation is completely different depending on the platform (indexed aviread is the most obnoxious I've found).

You can prove this to yourself if you want using the following code:

[fin, AVIpath] = uigetfile('*.avi','Select 420 AVI File');
UserAVIFile = strcat(AVIpath,fin);
avifilename = UserAVIFile;
fileinfo = aviinfo(avifilename);
nframes = fileinfo.NumFrames;
tic
mov = aviread(avifilename,1:nframes);
toc

Under OS X an 1800 frame .avi will take around 500s to complete the indexed read and under Windows it takes under 10s (note this is using OS X and Windows on the exact same MacBook Pro). The problem in this case is how the code was written for Unix/OS X platform. I suspect this type of thing is the underlying reason why so many functions are drastically slower under OS X.

I just hope that eventually MATLAB improves the speed under OS X because it is clearly a problem that Mac users are experiencing although Mathworks staff tend to blame the differences in speed on intangible hardware differences. I know this isn't the case because I've been able to reproduce the discrepancies on identical hardware by booting into Windows from the Macs I have access to.

This is specifically stinging me right now because I just spent $6000 on a new Mac Pro (Dual Quad Core Xeons with 16Gb RAM) and it benches and generally runs my MATLAB code slower than my 10 year old Pentium 4.

Regardless I still like MATLAB for all of it's positive characteristics I just wish things would run as fast as they should on the high end hardware I have.

I totally agree with Graham. I did all the stuff of the java.opts thing, and it can scroll down now and all that. Now when you have to work more seriously and put things to be calculated, I find my old toshiba laptop pentium 4, 2.5Ghz, 500MbRam Win Xp runs faster than my new Macbook with 4.0Gb RAM and 2.0Ghz. How the heck is that possible?. Is there any other fix I could do to recover all that wasted power from my macbook?. Where did the 4Gb RAM go?.

Brian, have you guys solved this unpleasant performance problem?. Would things go better if I go back to former Matlab versions?. Now I am running 2008a.

Thanks!
