I feel like Ive tried everything and I cannot seem to fix this problem Ive had for a while now. Everytime I right click a file and try to use "open with" I get a spinning beach ball and it won't show any of my applications for about 20 seconds. It also takes about a minute just to boot up after the login screen. The dock will show up right away but if I try to open any applications they are un-responsive for about a 45 seconds. I am also getting system hangs at random times that freeze everything no matter what it is for about 2 seconds. It happens about every hour and I searched the console messages but can't find anything when it happens. My mac used to be fast and reliable but now it's starting to feel like Winblows 😟. I also made a new user to see if it fixed the problems and it did for about 2 logins but after that it started to slow tremendously and there was a huge difference in speed from when I first added the new user.
If anyone could help that would be awesome because I feel like I have tried everything with no luck.
Here is what Ive tried so far.
Repairing disk permissions + resetting ACLs on home folder.
Deleting all caches and system logs with Mountain Lion Cache Cleaner.
Reset the PRAM and SMC
Ran daily, weekly, and monthly maintenance scripts
Removed all login items
Updated prebindings, Locate Database, and rebuilt spotlight.
Unchecked "put hard disks to sleep when possible" in energy saver.
Re-installed the OS using Mountain Lion's built in recovery disk.
Checked the smart status of my drives.
Thats all the sutff I can remember off the top of my head and nothing has worked so far.
The only thing I can think of would be to erase my HD and re-install a fresh copy of Mountain Lion, but the last time I did that it took months to get everything back to the way I had it. I had to re-download all my apps and all the settings and preferences for each app plus serial numbers were gone.
The sad thing is my old iMac from 2005 is faster then this one at logging in and other things. Finder seems to be faster and snappier on my old iMac. Programs open faster...
I feel like I know more than the average person about macs but I just can't seem to figure this out.
If anyone could help that would be awesome!
Thanks!
