Update:
So Ive been subscribed to this for a while now and thought Id give an update on how Lion is still plaguing me with the beachball. Search my other posts for the history.
As mentioned before I installed 4Gig RAM, New Momentus XT HD 750Gb, fresh install of Lion. All good for a month or so or longer but the beachball returned....
As much as I would love to have Mountain Lion installed, Apple will not allow it on my Blackbook even though it could probably run it. i cant afford the price of a new Mac just to have my mac run the way its meant too. With Apple not admitting to any problem on older hardware its hard to see if we are going to see any solutions soon. very poor on Apples part but heres what Ive done.
I have Tech Tool Pro 6 and decided to run that to see if it would come up with any major issues. I created an edrive on a seperate drive and reboted into the eDrive and ran the Tech Tool program. It found a multitude of problems. Particularily a heavily fragmented drive. And I mean HEAVY! it took over 24hrs for its to run File optimizer, then Volume optimizer then Volume rebulder and after using for the day I have noticed not one Beachball.
Now whos to say that it will last but at least I have TT6 to carry out the required maintainence to get the drive back on track and stop hang ups. I may run it once a month just as a matter of course. It shouldnt take the 24hrs+ now like the initial scan and rebuild. I have checked that the Secure VRAM is on and it is but i dont have my RAM being eating up to the extent that it hangs. Ill update in another month or so. I would conclude though that even a fresh install of Lion is rather scattered and untidy and thus the beachball is appearing within days or weeks for some users.
i would love to go back to Snow Leoapard but Apple being Apple they have me so heavily involved with iCloud that I cant go back that easy!! Ive managed to keep the messages beta on my mac too even though the trial has finished and that has proved invaluable. Why cant Apple not make certain features available to those people that cannot upgrade to ML because Apple dont allow the hardware? At least make it a bit easier to be part of the crowd instead of rubbing Lion users noses in it and saying "Get a new Mac" that is a luxury that I simply cannot afford.
If I can sustain a stable Mac for the month then Ill know that TechTool6 made everything ok. And Apple dont actually stand by their software that much if it takes a 3rd party to make their OS run more efficiently.
Hope this helps others. Sure as **** Apple aint gonna help!
