Have been using my MacPro for about 18 months and it's been almost flawless ... until the last few months. Seem to be experiencing all kinds of strange system behavior, like:
- applications sometimes freeze when using File->Quit
- sometimes when I select "Restart" from Finder menu (espec. after a force-quit of app), everything on the desktop disappears EXCEPT for my wallpaper and the system never reboots
- when viewing Finder windows in Column View, often it takes a loooong time for subdirectories to appear
- lately, when I reboot, the grey screen with the Apple logo and rotating wheel stays for ... maybe 2 minutes or more? Then it goes to a blue screen for about as long before giving me my desktop
- backup to Time Capsule (via WiFi) runs very slow and sometimes interferes with the network
Here's what I've done:
- rebuilt permissions a million times
- ran Repair Disk a hundred times (no problems)
- ran Onyx and cleaned caches and Launch Svcs database and other things
- ran Apple Hardware Utility (no problems)
- pared down fonts that are loaded into the system at start-up
I have an older version of Disk Warrior that is showing my hard drive to be fairly fragmented. I'm wondering if I updated DW and de-fragged the hard drive, it might improve system performance (?) Someone recently told me that de-fragging is no longer necessary since OS does this on its own. I'm NOT a techie type person and am clueless about such things.
I have four internal 1-Terrabyte hard drives, none of which is more than 25% filled.
I'm still using Snow Leopard since I have apps that are not Lion-compatible.
Any ideas or suggestions?
