Solved | Snow leopard Freezes or application hangs in snow leopard?
I was a victim of the same and figured out the solution on Saturday and have been using my system for 3 days now without any issue.
Who should try this hack? If any one is true for you its worth trying.
- You have recently upgraded your RAM from 2GB to 4GB or above.
- Your MAC Book Pro or what ever mac machine came with Leopard and you just installed snow leopard from somewhere.
- You tried formatting and various stuffs still Firefox and Safari hands and various programs becomes “Not responding” and you need to kill them.
Ok then you should try.
Before doing that just check the following:
Thats all.
Now open Terminal (Finder and type terminal ) and type the following.
sudo systemsetup -setkernelbootarchitecture x86_64
It will ask for your administrator password. Provide it and restart your machine. Voila!
Facts:
Open activity monitor and see all the default apps has started as 64Bit now.
Nice to see its working for people :)
Hello I used this tutorial: http://classictutorials.com/2010/08/snow-leopard-f...
to boost my performance and it worked great except that I have a clear USB modem and after the restart It would not recognize the modem. I reverted back and it worked fine and in the activity monitor everything but the clear connection program was 64 bit. Any idea how to make the modem work after executing this change? Thanks in advance - Colby
Ya some softwares doesn't supports the 64bit Kernel. For me the Cisco VPN doesn't works if i do the same. I talked with CISCO and looks like they are coming out with some update. So two things you can try.
1) Uninstall the software. Then put the hack i gave in the tutorial. Reboot and reinstall. 60% chance it should work. I was able to so the same for a webcam software.
2) Contact the manuf. :(
Ok i tryed it but didnt work for me apps still stall but not as bad as before. how do i go about changing it back?
You can revert back with this.
sudo systemsetup -setkernelbootarchitecture i386
Thanks for your help here. Makes sense and I have been attempting to do but the changes to the system do not seem to stick. We have multiple users on this machine...would that make a difference? Thanks
I tried with single account though. Let me try with multiple user. But ya you need to run the command as the administrator. Else you can try running sudo su in terminal and then execute the command.
KD, after speaking to you on the phone, I check my start-up setting and realized it was in 32-bit mode, but I haven't faced this problem so far, never-the-less I've changed it to x64 now, let see if it gives me a performance boost ;)
Ya.. Best part is.. just after restart open the activity monitor.. You will see all the default apps started as 64bit.
Cool, good information, thanks a lot.
Thanks dude. Nice to hear from u in my blog.
Ya worked for me. thanks a lot
Ya this worked. I searched every where and there was no solution which worked except this. Thanks a lot. It was the x64 problem.
