My current problem is that I cannot play MP4 files sent to me on my computer but I think I should plan for the future and get something that can read and play (or convert) many types of audio files. Now, as I have 10.12.6 and I'm unable to download a later operating system due to hardware limitations of my iMac, I'm wondering if it's possible to download an earlier version of Garage Band that will work with my iMac and how do I go about doing that?Īlso, I'm looking for something that can play various audio file formats on my iMac or convert audio file types so I can play them, listen to them.

I looked into downloading Garage Band on the internet and the download is free but the current version of Garage band being offered is 10.3.4 and the download info says you must have Mac OS 10.13.6 or later to use this version. Now, I thought that Garage Band came bundled as part of the operating system download but apparently not in my case as I don't have it but I would like to start using it. This version of the operating system was installed onto my iMac at the Genius Bar/ Apple Store about 18 months ago.

IMAC 2011 OS HIGH SIERRA 10.13.6 UPDATE

I ran a security update in November without a hitch, but since running the last update earlier this month the system has been prone to very slow system boots and boot freezes, so I have made a USB installer using the latest download and patches and intend to re-install the system.I have an iMac and I'm using Mac OS Sierra 10.12.6.

I installed a later Atheros Wifi card shortly after buying the machine, as the machine came without Wifi, and there have been no problems with High Sierra and WiFi.ĭosDudes Patch Updater allows AppStore system updates to run. This never caused any problems in El Capitan, but seems to be the cause of the random logouts, as they haven't occurred since I removed it. I have an unflashed EVGA Nvidia GTX 760 which performs well, and gives me CUDA in Photoshop and After Effects, but when problems do arise it's handy to be able to see the EFI boot screen, which I can't do with the PC Nvidia card, so I left the old ATI Radeon 2600XT installed powering a small monitor. One fault that took me a while to fix was random logouts for no apparent reason, but I pinned it down to a conflict between my GPU's. Has been relatively problem-free, though sometimes feels slower than El Capitan. I have been running High Sierra on my 3,1 2008 8-core Mac Pro since September 2018, using DosDude1's installation. Since I already did a hack firmware update, I'm afraid to do this yet until I know more about it.

IMAC 2011 OS HIGH SIERRA 10.13.6 INSTALL

Warning I went to install it on an internal SSD and it says it wants to do a firmware update. I just booted this same machine from a High Sierra install on an external drive and it is what I'm using at this moment with no apparent issues. I have had no issues with this installation for the last year. Here's how I initially got my Early 2009 Mac Pro to take 10.2 Sierra:ĮFI and Firmware update from 4,1 to 5,1 for Sierra Upgrade Solved The 2007 iMac 7,1 is compatible if the CPU is upgraded to a Penryn-based Core 2 Duo, such as a T9300. Early-2008 or newer Xserve (Xserve 2,1, Xserve 3,1) Early-2009 or newer Mac Mini or white MacBook (Macmini 3,1, MacBook 5,2)

Late-2008 or newer MacBook Air or Aluminum Unibody MacBook (MacBookAir 2,1, MacBook 5,1) It is reported to work on theses unsupported machines: Here's the patch tool by dosdude for High Sierra, Iused his former patch to do the Sierra upgrade. I did open a new install of MS Office 2011 which had reports that it was not going to work but so far have seen no issues. I did my first install of 10.13 last night on a 2012 13" MBP without issue as expected but really have not looks at it yet.

I posted this to see if anyone has done it yet, also because I know we will have question on it, and to see if anyone has attempted it yet and has any advice. I'm first going to try the install on a 2008 MacPro, then try it on either a 2008 and/or early 2009 MacBook Pro. But, after watching a couple of videos, right now it appears I will not have to do a firmware update. At the time I did it last year, it appeared that it couldn't be done on the 2008 MacPro. I did the Sierra upgrade on a couple of MacPros 4,1 and it has worked excellently, after I did a firmware update patch to get it to read as a MacPro 5,1, so I am very optimistic on doing it again.

I am currently researching installing OS X 10.13 High Sierra on unsupported Macs.
