Mathematica starts badly 1 time over 5 in OSX
in [Mathematica]

From: Nicola Mingotti on 26 Mar 2010 06:35 Helo, I'm using Mathematica 7.0.1 for students in OSX 10.6.2 and it works really nice ... when it starts. The problem is that sometimes when i run Mathematica the kernel doesn't start well and i have to restart, i can't even do a single computation. This happens one time every 4-5 run of the program. After a crash, at the second run, Mathematica has always started well. This behaviour has been observed at least 20 times since now. Does anyone else have this problem ? Thank you Nicola
From: James Stein on 27 Mar 2010 06:10 I use Mathematica 7.0.1 (home edition) in OSX 10.6.2; it always starts up fine. I assume you've restarted your Mac and the bad behavior persists. You might try starting your Mac in safe mode<https://support.apple.com/kb/HT1564> (about which I know very little); Regardless whether this stops the symptoms or not, you may gain information. You could reinstall everything (starting with the OS); sadly this is a tedious chore. - Show quoted text - On Fri, Mar 26, 2010 at 3:35 AM, Nicola Mingotti < n-no-mingotti(a)g-spam-mail.com> wrote: > Helo, > > I'm using Mathematica 7.0.1 for students in OSX 10.6.2 > and it works really nice ... when it starts. > > The problem is that sometimes when i run Mathematica > the kernel doesn't start well and i have to restart, i can't even > do a single computation. > > This happens one time every 4-5 run of the program. > After a crash, at the second run, Mathematica has always started well. > This behaviour has been observed at least 20 times since now. > > Does anyone else have this problem ? > > Thank you > > Nicola > > >
From: Syd Geraghty on 27 Mar 2010 06:11 Nicola, I have observed this consistently after the last major update of Snow leopard from Apple about 4-5 months ago if my memory serves me. I almost always find that after aborting the first evaluation when it appears slow and then re-evaluating the problem disappears. I presume WRI is aware of this behaviour and will fix it in the next much anticipated release. Cheers ....

Mathematica exhibits this behavior typically after a system reboot in the current version of OSX. If one reboots, and then starts Mathematica, there is no response to a computation. If one quits that mathematica session and then restarts Mathematica there is no problem -- and there generally is no such problem again until one reboots OSX. I assume that this is fixed in the next version of Mathematica... I am sure that john Fultz could comment. --David > The problem is that sometimes when i run Mathematica > the kernel doesn't start well and i have to restart, i can't even > do a single computation. > > This happens one time every 4-5 run of the program. > After a crash, at the second run, Mathematica has always started well. > This behaviour has been observed at least 20 times since now. > > Does anyone else have this problem ? > > Thank you > > Nicola

NO. There is an issue accessing the help system directly immediately after starting, but the app itself works fine, with no problems starting, opening and using notebooks, etc. You may wish to start up holding down the option key to essentially 'reset' Mathematica. Failing this, you could drag the app and preferences folder(s) to the trash and re-install. If you dump the prefs file, you will need to re-enter the password. george On Mar 26, 2010, at 6:35 AM, Nicola Mingotti wrote: > Helo, > > I'm using Mathematica 7.0.1 for students in OSX 10.6.2 > and it works really nice ... when it starts. > > The problem is that sometimes when i run Mathematica > the kernel doesn't start well and i have to restart, i can't even > do a single computation. > > This happens one time every 4-5 run of the program. > After a crash, at the second run, Mathematica has always started well. > This behaviour has been observed at least 20 times since now. > > Does anyone else have this problem ? > > Thank you > > Nicola > > |
