You can get help here faster if you use your Profile and include your computer, OS X version, memory, and storage. What year is your Mac mini?
The response will vary depending on those values.
Two things you can do initially:
- Use Disk Utility to verify/repair permissions on your boot drive. Also select verify disk.
- Boot into Safe Mode to clear caches and rebuild certain databases.
- Normal mini shutdown.
- Press and hold the shift key with new boot
- Release shift key when grey progress bar appears
- At login prompt
- password. Stop.
- press and hold shift key while logging in
- release shift key when desktop appears
- reboot normally
Does your mini still run slow after the above?
That's it until you share more.
Here is what I believe you have.
Late 2009 Mac Mini 3,1 ( w/2.26 Ghz Core 2 Duo (P7750) CPU. You also likely have the Nvidia GEforce 9400M GPU with either 128 or 256MB VRAM. Your 2GB (2x1GB) of main memory is 1066 Mhz SDRAM PC3-8500 DDR3 SO DIMMS (204 pin).
Despite what Apple suggests, your 2GB of memory will cause very poor performance with Mountain Lion. I would recommend a single 4GB (1x4GB) memory module, the official maximum, or with the EFI v1.2 firmware update, you could add an additional, single 4GB module for an unofficial 8GB of memory. Do not leave one of those 1GB memory cards in with the 4GB replacement. That 4GB memory module runs between $31.99 and $32.99 here.
There will be a noticeable performance improvement in boot time and operational speed with that additional 4GB memory.
The steps that I previously outlined may also contribute to performance improvements.
Hi Viking OSX
Firstly THANK YOU for your help.
I have took Avira off and it seems faster. Also did the "Disc utility verify/repair thing and it said its ok.
I will take your advice on the upgrade of memory. I looked at the apple web site help and is seems to say I need a professional guy to do it.
I installed more memory on a pc I had years back and it speeded that up but I don't fancy opening the Mac Mini and doing it my self.
I have not done the "Boot into safe mode" procedure because;
1. it seems to be running ok and
2. I am scared!
Some time ago I had a similar slow running problem and a friend installed "Maintenance" from app store. He said it cleared the cache. Don't know if that was true but Maintenance does not work on Mountain Lion.
Thank you Again
Safe Boot Mode will not harm your Mac, your Mountain Lion installation, or your personal files. It is a standard Apple maintenance procedure, actually inherent to the operating system, that cleans out cache files (that will be recreated), rebuilds the font database, checks the filesystems for errors, and a few more steps. Other than the steps I previously outlined, it does all of this before the login prompt. Very simple actually. You should do this.
I have a 2011 Mac mini which requires one to rotate the plastic circular cover on the bottom and the memory slots are instantly available. Memory replacement on the 2009 Mac minis would not be something your nervous system could withstand. You want to take this to an Apple store, or an Apple Certified Reseller that has trained service staff to do this for you. Here is a video on the process, done by OtherWorldComputing, one source of memory that I provided you earlier.
