My mac has several problems, running very slowly being the greatest. I have decided for that reason and a few others that it will beneficial to format my Mac.
However, I do not have the installation disk.
So the question question remains as is the title:
How do I format my Mac without the installation disk?
2Without the disk there is no way to reinstall. Maybe apple can get you a replacement or you can take it to the genuis bar. – Daisetsu – 2011-01-03T22:27:01.630
any suggestions with how to improve performance then? – RSM – 2011-01-03T22:28:12.097
2Create a new user account in System Preferences. If that one is also slow, it's a system/hardware issue. But if that account is faster, you have too much crap in your user profile. Uninstall software, remove Login Items (also in System Preferences » Accounts), remove Dashboard widgets, menubar utilities, etc. Safari also doesn't like lots of bookmarks, for example. – Daniel Beck – 2011-01-03T22:33:39.767
Not that it answers the questions directly, but I had slowdowns with my MacBook Pro, and it turned out the be the hard drive. I downloaded SmartUtility on the recommendation of Spiff's answer in http://superuser.com/questions/357308/what-is-causing-the-atrocious-performance-of-my-macbook-pro and I haven't looked back
