  Hi, I have an iMac 27 "(mfg mid-2010) bought in Singapore." I travel in North America. The computer is still in good condition and want to know if I can take it. For most electronic devices, the different current/voltage in North America that makes them more or less useless, but laptops, for example, have the adaptability between the two parameters of current/voltage. The iMac has this capacity? The food fits North American power?

  Yes, he does.

• Update the iMac 21.5 mid 2010 "with SSD

  Hi - I am interested in upgrading my iMac 21.5 mid 2010 "with an internal SSD. Have been reading the posts on the subject and I wanted to clarify a few points. As I understand it, there is not a spare drive Bay, so my options are to replace the existing drive, or replace the optical drive.

  My questions are:

  (1) is there a difference in meaning in performance in both options?

  (2) the location of the optical drive is a stable position (physically) to put a SSD?

  (3) if it is placed in the location of the optical drive, I'll be able to boot from the SSD drive?

  (4) I read that if you replace the hard drive, there is also a problem with a heat sensor that fans end up running a full speed, and you must download a software workaround solution, or get a special thermal sensor OWC. This applies also to put it in the optical Bay? Why or why not, and if not, is the drive always properly cooled? Not sure I quite understand that part.

  Thanks for any help,

  David

  I added an SSD for my iMac 2011. It has an extra SATA port, so I could leave the optical drive in place and put the SSD in behind it, while keeping the original HARD disk too.

  I think that 2010 models do not have this port, but the other World Computing would be able to confirm this on their site based on the available kits.

  1. you won't see any difference in performance in both positions. Note, the 2010 iMac uses ports SATA 3 G, so if you use a 6G SSD, it will only run at 3G speeds. Willl you always get a huge performance on the old HDD even gain at this slower speed.

  2. Yes, to use the available kits

  3. Yes the installer once you define which drive you want to boot from in system preferences > startup

  4. I think it's only valid for 2011 models, but still OWC kits will show if you need the adaptor cable. It does not apply in the optical drive. Cooling still works correctly if you use the kits to correct or additional software.

  Edit: just check out OWC, it seems that the thermal cable adapter is required for this model

  Edit 2: If you have never worked on electronics, I strongly suggest that you do not open the iMac yourself. If it is not particularly difficult if you are experienced, it is very easy to break something if you do not have this experience.

• Blocking problem down an iMac 21.5 mid 2010

  I have an iMac 21.5 mid 2010, with El Captain 10.11.3. When I try to stop, he stays with the wallpapper in the office without the apps, but he doesn't stop. Can someone help me please?

  Next time you start your iMac again boot into Safe Mode, Mac OS x: departure upward in Mode safe. This will work some diagnostics and repairs on the iMac when starting upwards.

  Stop and see if it does as it should.  Restart normally and try to stop again.

• 10.6.8 resettlement on iMac 21.5 mid 2010

  Good afternoon everyone!  I was given a used iMac 21.5 mid 2010 with OSX installed 10.6.8.  However, I tried to clean this computer completely to remove all information of the previous owner, connections, etc.  In my efforts, I discovered that the optical drive is functional (probably why I was given the machine lol).  I also discovered that 10.6.8 does not have the feature to reinstall from the internet (command-R).  I tried the optical drive on my Mac Pro Tower sharing, but apparently it does not work if the machine trying to share has an optical drive (work or not apparently).  I managed to create an installation USB (USB 3.0 Flash Drive, 16 gig) using my DVD of Installation of Snow Leopard existing.  However, when I start the iMac in Mode safe mode and then run the install from the USB key, it's going well for a few minutes and then falls into the white screen with the apple logo.  I'll be patient and let Cook awhile or am I out of luck?  Thank you very much in advance for your advice!

  Why not just get a DVD external burner (I'd purchase OWC) and install from there? This is the good method to use if the internal SuperDrive does not, either that or replace the SuperDrive.

  NOTE:  I just thought of another method, using target disk Mode to install. Connect the two machines together using TDM and then do an erase and install. If for any reason you are not familiar with the TDM please click

• Will be my imac 27 inch mid 2010 - support Cuda

  Hi, forgive my ignorance here, but basically, as I see after effects CC needs a better ability to the graphics card.

  When I start the CC AE, it refers as needed Cuda - to Ray traced rendering.

  Now, I have since downloaded Cuda - question is ' will it work with my iMac? (write below)

  * imac 27 inch-mid 2010 - graphics ATI Radeon HD 5670 512 MB

  All advice would be greatly appreciated as it seems the Ray Traced rendering is unusable without it, hope I'm wrong

  See you soon,.

  Simon.

  You don't want to use the rendering of the traced to the RADIUS. The ray-traced rendering engine is now obsolete. Use Cinema 4 d instead. It's free with AE CC, it makes it faster and it is much more powerful.

• iMac 21 inch mid-2010 with OSX 10.9.5 4 GB

  Have inherited an inch Imac 21 mid-2010 with OSX 10.9.5 running - I don't know much about Mac computers so no idea if snow leopard etc or what!

  This iMac is not iCloud drive available to sync with the latest iPhones etc.

  Is it possible to upgrade the operating system on this iMac to run the latest apps & iCloud etc.

  Don't really know where to start...

  Thank you

  You have OSX Mavericks. The next OS is Yosemite 10.10 and 10.11 El Capitan.

  You can upgrade the free OS for Mac by the opening of the App Store on the computer. When you click on "Updates", there is a large window which shows the next OSX update for your computer.

  On a computer from 2010, the most recent operating systems may appear slower. It really depends on the State of your hard drive and also the RAM. With 4 GB of RAM, you shouldn't have a problem (every BONE just 2 GB). However, and the older hard drive may have trouble keep in touch with the requirements of the operating system, which makes the computer slower.

  The best thing to do is to make a backup of data is installed on the computer, then just go for it. Worse comes to worse you can always restore the computer with the back facing upwards.

• 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.

• 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

  k

  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...

• iMac mid-2010: list of compatible HARD drive

  Hello

  I need to replace the hard drive of my iMac 21.5 mid 2010. I thought that any SATA drive would work, but after studying a bit I discovered the issue of thermal sensor. So my question is: are there at - there somewhere a list of compatible drives? I can't find any information on this subject.

  I'm not going to replace the drive myself, but I would like to know the options.

  Thank you

  Luis

  You don't necessarily have to get a special player.  There are interface cables

  available that have a temperature probe attached to it.  See:

  http://eShop.MacSales.com/item/OWC/DIDIMACHDD09/

  This cable simply connects between the new drive and the cable of the iMac.

  Using this cable, you can install any available hard drive.

  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.

• Need help to install Windows 8.1 on the partition, bootcamp on Macbook Pro 15 "mid-2010 w / no optical drive"

  I tried for almost a week in all possible ways to get windows installed on a boot camp partition on my main SSD 1 TB drive as a partition, or on my HARD drive, which is installed in place of the optical drive.  So far, everything I tried to give me some sort of error at some point in the process.  It seems that many of them are case by case, so I thought that I invite you all and see if you can help!

  I use a Macbook Pro 15 "mid-2010 that I improved with a 1 TB SSD drive as the startup disk.  My optical drive was not functional, so I moved my old 500 GB HARD drive to the location of the optical Bay.  I am also under the latest version of El Capitan (10.11.6)
  Here are my system specs:

  
  Presentation of the material:

  Model name: MacBook Pro

  Model identifier: MacBookPro6, 2

  Processor name: Intel Core i7

  Number of processors: 1

  Total number of cores: 2

  Memory: 8 GB

  Processor speed of interconnection: 4.8 GT/s

  Boot ROM version: MBP61.0057.B11

  Version of the SCM (System): 1.58f17

  What I tried (from what I remember):

  I tried to change the Bootcamp info.plist file for my version of the macbook pro to use a USB stick for the installer.  It seems to have installed correctly but once I partition the disk and restart the computer, it gets stuck on a white screen with the Apple logo and I am forced to make a hard stop and then hold down option to boot into OS X, recovery, or the EFI Boot.

  If I go through the windows installation to start the EFI system, I get an error of:
  "Windows cannot be installed to this disk.  The selected disk is a MBR partition table.  On EFI systems, Windows cannot be installed on GPT disks. »

  I also tried to create a partition by using disk utility, and that too made me an error in the installation of windows.

  So far, the only way that I'm away from windows to run at all has been using the free trial of VMware Fusion 8... but I intend to use windows for more intensive tasks like audio pro, and merger simply does not offer the performance necessary to run these programs.  I'm hoping to install windows 8.1 on my internal SSD or HARD drive, regardless of the work - as long as OS X and files associated with it are left alone.

  If someone could help me please understand this point, I would really appreciate it!

  Thank you

  If your computer has an optical drive, you must use the optical drive to install Windows using Boot Camp Assistant.
