Install Mojave On Older Macbook

Comments

Mac Pro 7 1 Mojave

• pls direct me to the right forum is the following question is not to be posted here.

  I downloaded the patch version dosdude1 Current version: 1.1.2.

  Created the flash drive and got a successful complete.
  

  Tested on a Macbook Pro mid 2011 and a new hard disk.

  The installation bar goes to the end and stays there, waited for a long time and have to shutdown the computer.

  I used Mojave Beta2 and i don't know if this is the problem. the dosdude1 version suggest the latest.

  So what Mojave beta works with Dosdude1 current version: 1.1.2?

  anybody
  

  P.S. I know there some old version of this tool, which one will work?
• I have a 2011 iMac, cant i just upgrade the chip, ram and graphics card to make it work?

• Not Happy, I have a iMac 27p SSD I7 mi-2009 fast, and NO MOJAVE UPGRADE, disgusting, Authorize only Mac's after 2012, that is 6 years old, use not acceptable when you think that your machine costs 4000 dollars, even Microsoft does not do that

  A Mac is not a Phone !
  

  I can understand that some features cannot be available, but the FULL release not available without a good technical cause cannot be accepted without fight.
  

  Is there an association there that could issue a class action to claim for Mojave support for our not so old Macs ?
  

  I have a 2009 PC with the latest Windows 10, Is not Apple ashamed to issue a Mojave is forbidden to a perfectly fast and modern machine like the iMac mid-2009 ? Same for MacBook Pro ? same for MacBook Air ? Please Steve come and clean their minds.
  

  We have to make the buzz on Social Networks and Mac information sites, If not the delay will be 5 years, then 3 years, then 1 year and we will have to go back to Windows PC.
  

  Best Regards
  

• Not Happy, I have a iMac 27p SSD I7 mi-2009 fast, and NO MOJAVE UPGRADE, disgusting

  Last it seems that there was a deal with Microsoft to use a microsoft antialiasing software up to 2017, this would restrict Apple Mac OS to Retina display, may be this is the real reason for discarding more that 5 years old Macs that are not Retina, a number of users having non retina screens (external ),are claiming that fonts are ugly with Mojave !!

  So do not upgrade to MOJAVE if you have non Retina external display, try it with a Dongle.

• That is correct, and is exactly what I do, OutdoorAppDeveloper I would like to add a question. What if you upgraded the RAM and switched from an HDD to an SSD, would it be ok to install Mojave on a 2009 Mac with all of these upgrades?
• I did this but now the MBP (early 2011) start complaining about hardware accelaration not turned on. Any ideas?
• I have an iMac mid 2011 and I really intend to buy a new one. But for now all I can do is update it to Mojave and upgrade my actual RAM and change disk to SSD.
• I attempted using macOS Mojave Patcher v1.2.2, downloaded Mojave as instructed, created the USB installer however after rebooting the USB installer could not be seen. There’s no way to boot from it at all, any ideas?

• There's a compelling reason for installing Mojave on my mid-2009 MacBook Pro: Adobe Creative Cloud 2019 will not install on any older versions of MacOS. DosDude's patcher worked flawlessly, and the only problem with the update is cosmetic; the menu bar has a grey tint. I was able to install CC 2019 and it works perfectly.

  You can disable transparency and then it'll work normally.
  system preferences>accessibility>Display> enabling 'reduce transparency' removes the 'greying out glitches in light mode.
