Last boot from off took about 11 minutes. Once booted imac works OK. This slow down has been in the last month only. How do I speed up the process? I have tried repairing permissions, repair disk, and maintenence utility. These test are very slow and no improvement seen. I have 3 gb ram.
Thanks.
iMac, OS X Mountain Lion (10.8.2)
Could be several things, first 3GB is not enough RAM to run Mountain Lion efficiently, your machine should have at least 3GB of RAM. Also your description sounds like a possible failing HD, before you do anything backup the computer and run Apple Hardware Test in Extended mode 3x.

Thanks for the reply and suggestions. Instead of running the disk utilities in recovery mode, I ran fsck in single user mode thinking that it would be more powerful. I did have to force a start, but the results revealed that the HD was acting properly. I ran repair permissions, and oddly it found nothing. I am ordering a 2gb memory stick to replace the 1gb stick. Now I will have a total of 4gb, which is the max for my imac.
At this point I will be waiting for the new ram to arrive.
Thanks for your help.

Your machine can probably accomodate 6GB, check out www.macsales.com. My old 24" had 6GB in it for years, that extended it's life by at least another 2 years for me.
Thanks. I thought that 4gb was the max for the 7,1 model (Mid 2007 20").

4GB is what Apple states, however many have found out the understated the maximum capicity. You can have a 2GB and 4GB DIMMs installed to total 6GB.
RAM may or may not solve all of your issues.
How full is your Mac's hard drive?
If there is less than 20 GBs left on your iMac, it maybe time to start archiving and cleaning off your iMac's hard drive.
How many applications do you run simultaneously in the background while working in another application?
Do you run any antivirus software on your Mac? Antivirus software can slow down the normal operation of OS X.
Do you run any "crapware" like Mackeeper or any other type of so called hard drive "cleaning" apps?
Thank you for your suggestions. I will check out some programs to learn how much ram is being used. The HD is less than 1/2 full.
I appreciate the time you spent on my problem.

Thanks for the information. I have not seen any of these links. I realize that my hardware is aging and the last certified for Mountain Lion. Previous to Lion, I depended on AppleJack for maintaining a relatively clean Mac.
I printed out the links and will spend some time to learn what the authors recommend.
Thanks,

If you are opening your machine, you may also want to check into replacing the system drive with an SSD instead of an HDD. You can get 250GB SSDs for under $200 USD many places and that can have a huge impact on your system boot performance.
Very slow boot for Mt. Lion imac mid 2007. Want speedup.
