Reset foolproof Mid 2010 iMac

Hey people and our apologies in advance to those of you who are aware, I am the fool who needs protection against

I am trying to reset the iMac family as it has been rumbling along for close to 6 years accumulating all the usual garbage. Multiple users, multiple libraries etc. My feeling is to do a factory reset and then spend some time setting the system manually rather than Time Machine etc. I know it's rather long, but I want to make sure that whatever it is on the iMac is here to design rather than a hangover or an oversight. I will also be implemented as a user to avoid the trash in a triple that we had before.

so... the question is how to do the factory reset without risk. I took all the files that I want to disable external hard drives and I have TM backups too. My only concern is because it is a 2010 that I have more no disks. IS this a problem or I'll be able to use the Restorer online?

Machine - iMac (27-inch, mid 2010), 3.2 GHz Intel Core i3, 12 GB 1333 MHz DDR3, ATI Radeon HD 5670 512 MB, macOS Sierra 10.12

Thanks in advance

If the computer is running Sierra what you can do is to restart in the recovery (command-R on startup) Partition

Then, open disk utility and erase the internal HD ATTENTION! This will clean the HD.

Then close THE, and then select install Mac OS and select the internal HD. This will install a clean version of Mac OS X on the computer.

Once OS X is installed, select Restart and make sure that you choose the HD internal as boot drive. Once the computer restarts with your new version of Sierra you can start to install your applications and restore your files, settings, etc...

  • mid-2010 iMac slower afer is upgraded to El Capitan

    Hi all

    I ran EtreCheck (thanks Allan!); details below.

    Also ran AHT & it showed no problems

    I installed an SSD in December machine considered fast - then installed El Capitan and he slowed, & I think it's gotten worse in recent weeks.

    Symptoms:

    • delays of beach ball
    • Some applications and files are very slow to open
    • using bluetooth keyboard & mouse - cursor seems to get hung up in emails, etc. (& same jumps around tasks randomly once in a while - JUST started using the mouse & keyboard cable; so far, not sure they are better.)
    • using iCloud for most documents.  The files are slow to open, but Cnet speed test shows that 20-30 MB/s download speed.

    I do not know is that a "clean install", but I had no problem (obvious) El Cap installation.

    With the SSD and 20 GB of RAM, this machine should always work for some time, Yes?

    Thanks in advance for your thoughts and advice.

    The only obvious thing that I see is that your RAM is installed incorrectly. It should be in pairs, your is wrong in pairs. The Bank 0 and Bank 1 should have identical RAM installed.   You also have a very old version of Parallels installed. If you use Windows yet then upgrade of Parallels and if you uninstall according to the developers.

  • manufacture of mid-2010 iMac long beep during use

    Normally this beeps indicate memory RAM problems. You can try to take a MEMORY first and see if it gets better. If this is not the case, try a different RAM and check if it makes a difference.

  • Only 2 available ram slots, not 4 on 27 inch Mid 2010 iMac i3

    Hello

    Well, I'm puzzled.  I bought an iMac 27 inch, Intel Core i3 mid2010 news about 5 years ago. In the about this Mac it says 4 slots available, with only 2 in use (2 GB each).  This week I took it to a technician to install additional RAM and we discovered that the slots are not available. There is a molding hard plastic over them and in fact with a closer observation, that we noticed that even if I had to cut the moldings for the ram to connect. The tech denounces with Mac every day, because he's never seen it before.

    I just called Apple directly, and they have no idea why this would be.   Anyone else out there he never heard of this?

    Thank you, Darrell

    See > install memory in an iMac - Apple Support

    Problem is that the Mac is very picky and not just any PC3-10600 1333 MHz modules will work.

    Your best bet is to buy for providers like OWC and Crucial memory modules that specialize iMac RAM.
