#MAC RUNS SLOW AFTER SIERRA MAC#
Immediately after updating to macOS Sierra, the Mac must re-index the drive for use with Spotlight and Siri, the built-in search functions in Mac OS. Read on to learn why macOS Sierra may be running slow (some MacBook users notice their Mac is hot and fans are blasting away too), and what you can do about it.ġ: Slow Mac After Sierra Update? Fans Blazing? WAIT! If you have noticed a performance hit after upgrading to macOS Sierra, there is likely a good reason for it, and it’s even more likely to have a simple solution. Once macOS is reinstalled, you will be asked whether or not you want to restore from a Time Machine backup during the setup procedure.Some Mac users who have updated to macOS Sierra have felt their computer is running slower than it should be. Once the SSD is in, macOS can be restored via Internet Recovery:

If you want to keep any of the data that is currently stored on your HDD, I suggest you create a Time Machine backup to some external drive.

If you don't think that you can pull it off yourself, then consider letting a Mac repair shop or similar do it for you. it requires a partial disassembly of the device. Please take note of the fact that the HDD -> SSD upgrade, contrary to the RAM upgrade, is very hard to do. This OWC kit contains such a thermal sensor:

The thermal sensor measures the temperature, and if you insert the SSD without also inserting a new thermal sensor, the fans of the iMac will be running constantly and at full speed, since the machine is no longer able to read out the temperature. The thermal sensor that is currently in your device is inseparably connected to the current HDD. SSDs are 2.5" in size, however, which is why such an adapter is needed: Furthermore, the iMac 2011 will need an adapter, as it currently has a 3.5" HDD inside. Your iMac mid-2011 supports any SSD that matches the following requirements:Ĭhoose a capacity that meets your needs. The RAM upgrade is very easy to do, you can take a look at the procedure here:

Apple never went back to update their info, so the wrong 16 GB RAM figure still swirls around. When 8 GB RAM modules became available, users found out that the actual maximum RAM capacity this machine supports is 32 GB RAM, this is also being confirmed by the Amazon reviews of the modules I suggested. You may find information online which states that your iMac 21.5" 2011 only supports up to 16 GB RAM (4 x 4 GB RAM modules), but this is outdated information! As 8 GB RAM modules were not commonly available back in 2011, Apple could only test with 4 x 4 GB RAM = 16 GB RAM. Here are some examples of RAM modules that work flawlessly in the iMac 2011: The iMac 2011 needs RAM that matches the following specification: A higher total amount than 32 GB RAM won't work due to a limitation in the logic board. It has four RAM slots, meaning four RAM modules in total will fit in. The iMac 21.5" 2011 supports up to 32 GB RAM (4 x 8 GB RAM modules). Well, there are two upgrades you can add to the iMac: You can add more RAM to it and upgrade the internal HDD to an SSD. Thank to anyone that would take some time to help ! the SDD options is the more ''viable'', but I am no Mac expert and I don't think they will want to buy a SSD juste because of an update. backing everything, then changing the SSD for a HDD, then restoring with Time Machine.įor more details, the only time machine backup I did was recent, after installing High Sierra so I can't juste restore with a backup to get Maverick back with everything. formatting the Mac, installing a new OS version, as for the first option, Maverick or a more recent one. This would be the best option if possible because that is the less risky and time consuming. I heard to restoring this way does not delete the files I have on the Mac and the applications, but I'm not really sure about this. restoring my Mac to the original OS (with macOS Recovery), then re-updating to Maverick (or a more recent OS version that would not be slow). From that I think I have a few options with are : For real opening any app take so much time it is almost unusable. Since the update the Mac is going so-fcking-slow.

Before the update it was running smoothly, not fast but there were no problems. I recently updated m’y parents's mid-2011 21'' iMac from Maverick to High Sierra. Hi guys, I am encountering a problem here :
