The Imac gets that spinning ball over and over and has become very slow. I updated to Yosemite and have 4 MGs of memory. My hard drive is ok per disk utilities and is not full. I have a ton of music and Itunes is always playing something but the music is stored on an external hard drive.
I opened Activity Monitor and 3 items seemed way higher than the others in the CPU Time. They are WSDaemeon, Kernel_task and Window Server. I googled all 3 and don't understand what they do but it seems I should not be doing anything with them. At the bottom of Activity Monitor is System which always shows a negative percentage.
Everything is very slow whether its the web, Itunes, Excel, etc. For what it's worth, I have Webroot Secure Anywhere which shows no virus or malaware and this also take a very long time for a scan.
I'm not a techie or an exotic user. Any help would be appreciated. The Imac is about 7 years old and I'm wondering if it needs to be replaced.
Is 4 gigs of RAM enough now-a-days? You might consider doubling it (at least).
I just assumed he was talking about RAM (because of the low number). If he is talking about disk space .... he is in big trouble. You better get that straightened out asap Sam.
Unless you backup your imac, and do a complete wipe and import your important files, you're stuck with it being slow.
7 years is pretty good life on it, i'd sell it in working condition while it still functions and just buy a new one.
That being said 4 Gb or RAM is pretty low these days. You probably also have an old spinning hard drive. Sounds like you're ready for a new machine. If you do want to hang on to the old one, the best upgrade you can do would be to go to 8 Gb of RAM. Should cost a couple of hundred installed from an authorized Apple repair shop.
IMHO webroot is useless. It wouldn't hurt you to lose that.
I had upgraded the machine from 2 to 4 GBs but I think 4 was the maximum. Thanks for all the help.
