Folks, desperately need some input on something which is driving me bonkers.
So massive Mac fans in our house. We currently own:
Mac Mini (late 2009) 2.26 Core 2 Duo, 4GB RAM, OSX Lion 10.7.4 (media centre)
13" MacBook (early 2008) 2.4 Core 2 Due, 4 GB 667 MHz DDR2 SDRAM, Mac OS X Lion 10.7.4 (interweb, e-mail, music room duties and general 'mule' as bough s/h a bit scruffy now)
24" iMac (mid-2007) 2.4 Core 2 Duo, 4 GB 667 MHz DDR2 SDRAM, Mac OS X Mountain Lion 10.8. Susy's design machine for when she's editing photos, using PAINT, anything where she needs a big screen.
20" iMac (mid-2007) 2.4 Core 2 Duo, 4 GB 667 MHz DDR2 SDRAM, Mac OS X Lion 10.7.4. My original machine, now used exclusively by George for his school work, movies, web etc.
13" MacBook Pro 2.3 i5, 8GB RAM, Mac OS X Mountain Lion 10.8. Susy's main machine now as she's out and about a lot. Her pride and joy, NO ONE TOUCHES THIS!! (unless she needs some help).
(note to self, STOP COLLECTING MACS!!).
Anyway, all our various machines are behaving perfectly EXCEPT the 24" iMac, which is giving untold problems. In summary:
Performance had been sluggish, with frequent SBBOD and opening of applications often very slow.
Completely failed after an attempted upgrade to Mountain Lion and would not boot, so I did an complete erase of the HD and total reinstall from Snow Leopard disk, and upgrade back up to Lion again but the crap performance and self same issues remain.
Things I have tried:
Running Mac Keeper and clearing all junk and reported issues
Verifying and Repairing the HD volume (even though no problems were reported)
Looking in vain at Activity Monitor to try and see if something was hogging the CPU (it wasn't) or if I had some of the claimed 'memory management issues' reported in connection with Lion - i.e. loads of Inactive and bugger-all Free memory. Sometimes this did seem to be the case (i.e. 2-ish gig of Inactive and almost zero Free), but other times not, even if it was still being really slow to open apps.
Please also note that this rubbish performance is not when I've got several 'greedy' apps (say iTunes, Aperture, Creative Suite) running, it's even when just Chrome, it's pants.
Oh and starting up takes ages too, particularly getting to the point when I can access the Applications folder.
Basically I'm stumped, especially seeing as my old MacBook which has the SAME processor and memory, performs perfectly which no problems whatsoever.
If anyone has any ideas, I would be most grateful to hear from you.
Cheers
