[doublepost=1486173913][/doublepost]I am having the same problem.
iMac circa 2009 (model imac 10,1), running 10.6.8
Last month installed new ram but was working fine since then,
Came back from holidays and started it up, was able to connect to new wifi network, opened chrome, but i think it started when i tried to browse to my first webpage (photos.google.com). Maybe something else though
No problems in safe mode.
Repeatedly get beach ball soon after booting up normally.
Removed all login items and peripheral hardware (just apple wireless keyboard, and tried difference mice)
Seems like the problem in this thread was not resolved?
Yesterday I rang Apple support, and after the initial wait on hold i was quite impressed at how responsive they were given my mac is close to 8 years old. But they could not fix it!
The philippines rep got me to try
- removing login items (i had already done it)
- removing items from /Library/LaunchAgents and /Library/LaunchDaemons
- ram reset (command option p r in startup)
- reset by removing power plug for 15 sec.
Then she ran out of ideas and transfered me to a guy in Idaho.
He had similar ideas as well as
- removing items from Library/Extensions, and /Library/LaunchAgents within my user folder
- running this command on terminal, which i terminated after no apparent progress about 5 hours later
> diskutil resetUserPermissions / `id -u`
Overall over an hour of phone support and more than that on my own. Was very impressed that the american guy called me back when my call dropped out after being transferred. He recommended a procedure (
https://support.apple.com/en-us/HT204904) to reinstall 10.6.8 but command r didnt seem to work on my mac.
Still the beach ball soon after starting up, and never any problems in safe mode. Except that safe mode is quite limited because hardware is disabled, such as (on my late 2009 21.5" mac) sound, graphics card (?), ability to recognise usb drives (so you can not do a backup!) wifi, i dont know what else.
I thought it was quite annoying that you couldnt progressively test the disabled hardware. I removed the recently installed ram, tried just the new ram, and put it back after it made no difference.
Then I had an idea
I disabled airport (wifi) as soon as it started up normally.
No problems!!
I can now use my computer offline, do backups etc, and know where to start for solving the problem. Kind of annoying how its so simple, and not having internet is a deal breaker, but at least my mac isnt a brick and i seem to have isolated the problem. Touch wood!
The wifi was always able to connect and it did work for short periods (definitely got some internet at some stage) but after disabling it i am not having the beachballs anymore, and it always used to happen within a minute or so of use since the problem started yesterday.
