I just purchase an iMac which was an open box item (only $60 cheaper) and noticed that powering up the system I would sometimes see the progress bar during the apple logo boot up. Once the system was finally up, I found the performance very slow so I check the activity monitor and saw that 2GB of RAM was wired! Meaning half my memory was required just to run the o/s. I would then reboot and everything would run fine (wired memory was only at 560MB). I should make clear that I would have this issue maybe every 3rd bootup (after system was shutdown)
After seeing this a few more times, I reseated the ram, still no luck. I then formatted the HDD and reinstalled Lion OSX…still having the same issue.I then conclude there was something wrong with the chipset, either on the motherboard, video, RAM etc. So I took the MAC back to best buy and explained the situation. Because I have apple care they replaced my iMAC with a brand new system (un-open box)!
Took home my new MAC and guess what my first bootup, I saw the progress bar and the wired memory was at 2.2GB!!! I then thought it was my outlet, replaced the power outlet in my house ran a volt meter to make sure there was no spikes, dipps etc. I also test the outlet while booting my old computer to make sure the voltage never dipped while power was being drawn. Every checked out to be fine.
Why do I see this progress bar and see high memory usage every 3rd or 4th boot up?
Is there bug or tweak I’m missing?
My old MAC NEVER had ANY issues (lucky if I had to use ctrl, option esc 5 times in the 5yrs I had the computer).
vEry ****** off at the moment.
