High Sierra Compatible with All Sierra-Compatible Macs

[Update: Apple’s iOS 11 Compatible Only With 64-Bit iDevices]

Apple made several hardware and software announcements at Monday’s WWDC 2017 keynote. One of the quieter pieces of news centered around Apple’s follow-up to macOS Sierra named “macOS High Sierra”, and it’s sure to please Sierra users.

Apple has not dropped support for any additional Macs, meaning High Sierra will be compatible with all Macs that are capable of running macOS Sierra.

  • Fingers crossed that High Sierra will be snappier on my 2014 Mac Mini. Sierra runs like a . A very slow overweight . I should upgrade the HD with an OWC SSD, but I’m not sure the cost would be worth it when I really should be saving for a 27″ iMac.

  • i wish apple would allow the RAM to be open and unlimited on all models and let us choose how much RAM we want or need so i do not have to buy a new computer every time mine is out of date. I have the original 2008 MBP one of the first ones. I cannot upgrade to the new stuff now. So i have a 2013 MBPR & 2015MBRP. I do not like how apple decided to cut us off with the RAM issue , not being able to UPGRADE any COMPUTER’S RAM is really STUPID. I pay the TOP PRICE for a NEW APPLE MBPR when it first comes out so i should get to choose how much RAM i want and be able to INSTALL NEW Ram. WHY do APPLE allow you to upgrade the iMac’s RAM? i don’t get it? WHY not the MACBOOKS or MBPR? to me its forcing the LAPTOP customers a PROBLEM and a headache. PRO MACHINES need at least 32 or 64 RAM these days with all we are doing on them. I am in MUSIC RECORDING and VIDEO so i need the max ram. I have spent $20,000 total with APPLE for iMacs and MBPR. I have purchased 4 i macs and 4 MBPR i might have spent beyond the $20k mark because i buy everything they put out like TIMECAPSULES i like to get MAC products because they work well together with no headaches. APPLE needs to STOP this NONSENSE with the RAM UPGRADE ISSUE on THE MACBOOKPRORETINA’S sorry it just is not fair that i can upgrade my iMac Ram but cannot upgrade my laptop ram. it’s my money i am buying your products let me decide what’s best for my RAM NEEDS

  • How about a 2009 Mac Pro with the MacPro 5,1 firmware? Fingers crossed!

    • Unfortunately, only 2010 and later Mac Pros will be compatible with High Sierra, according to Apple.

    • I run a prepress dept. at a printing company and we have 7 Mac Pro’s aging from 2008 to 2012 and one 2014 “trash can” Mac Pro. I have upgraded all the tower style Mac Pro’s with SSD’s from OWC and have upgraded to 32gb of RAM on all of them too and they all are running MacOS High Sierra with no issues…except for the awful Acrobat DC which crashes way to frequently. We got Sierra and High Sierra installed on 2008 and 2009 Mac Pro’s by using a patch installer found
      It works great just be careful to fully read the instructions!!

  • Listing some of these early models is laughable. Anything beyond Snow Leopard made them into slow sludgebuckets unless they have heaps of RAM and an SSD upgrade. Saying MacBooks can be upgraded is a joke!

    • Sierra is running ok on my 2011 MacBook Pro after I’ve upgraded it to 16GB and an SSD. It’s not that expensive to upgrade and performance is not hugely worse than the latest models.

  • This would be more useful if it said the earliest model # the new OS will work on. We can always use MacTracker for more detailed info re what OSX runs on what.

    I agree with Will et al, Apple’s adding frills for many of our uses and it complicates life because then we have to pay for all sorts of application upgrades to run with the new free OSX. These upgrades are costly! And doing all the upgrades are a time consuming process. A lot of the new features are good concepts but are either all on or off, limiting their usefulness.

  • macOS Sierra is a pain like no other.Why? It looks like
    Sierra has less intel than Snow Leopard.It is crashing at every turn.I remember Nokia in its last run was doing the same. Bad omen.Come on Apple don’t be a

  • A user Manual is needed for Sierra and then High sierra. i find many problems looking for new keystrokes etc.

  • This is excellent, easy to understand and useful information. Whenever Apple upgrades its MOS you should deliver similar well example and illustrated info. Even put a very small price or gifit tag to it and we consumers will contribute to Rocket Yard’s work.

  • I wonder if it will slow down my old macs? I am still using El Capitan for now. I wish they would make a streamlined, no-frills OS; all I care about is speed and simplicity and not superfluous features!

    • Sierra is a disaster. Honestly I think most of the updates since Snow Leopard have been steps backwards. I agree. I want something that just works.
