My iMAC is running on macOS High sierra 10.13.6 and I just purchased Turbotax 2020 and it won't open
because it appears I need at least 10.14. I have checked for updates on my iMAC, which is only 2 years old
and per there are not updates available. How can update??
iMac, macOS 10.12
The App Store Updates page only informs you of updates available for the OS you are running.
Installing a newer OS is called an upgrade.
Which OS you can upgrade to will be governed by which model and year your mac is.
Click on the top left of your screen click on About This Mac to find out the year of your mac.
For Mojave or Catalina,
Open Safari and click on this link,
How to get old versions of macOS – Apple Support
Go to Check Compatibility to see if your mac qualifies for the OS upgrade you want.
Then go to the Download OS section and click on the OS you want to install.
If you want to or are able to install Big Sur, open Safari and click on the link below.
How to upgrade to macOS Big Sur - Apple Support
Before upgrading make a full back up of your Mac.
Check that third party apps you use have updates available for the new OS.
Check that your printers/ scanners etc have updated drivers and software available for the new OS.
Connect your mac to your router via cable rather than rely on WiFi.
Do not use your mac while it is downloading
and do not use any other devices that share the same internet connection.
If the App Store says ‘Open’ then it is detecting a previous download of the install app
go to the Applications folder locate Install macOS ******.app.
Move it to the Trash, empty the Trash.
Restart, click on the link again, the App Store should say ‘Get' or 'Download'.
If you are considering upgrading to Catalina or Big Sur be warned they do not support 32bit apps.
Your Mac is probably running 32bit apps and these will need to be updated to 64bit apps,
some updates may be free, some may be paid. Use this app to discover which apps you have
are 32bit, https://www.stclairsoft.com/Go64/ then contact the developers of the software to see
if they are providing 64bit updates or alternatives.
Hi
I had same problem with TT 2020 and Big Sur 11.2.1. It would open in Jan and early Feb but will not open this week (2.21.21). Finally gave up on TT and just purchased H & R.
Hopefully they did their homework with Apple and did not leave a whole lot of Apple users in the lurch.
Shame on TT>

Turbo Tax installation
Hi
I did install TT Premier 2020 to my iMac running Big Sur 11.2.1 and apparently it is loaded
I worked from January till mid Feb 2021 and then nothing.
When I try to start it, the lead page of TT - 3 smiling faces- flashed by and that is it.
Apple did help me install it as well by creating a new User, where it did open but I could
not port over the File that I have on my normal folder which has all the ported over data
from 2019, etc.
There appears to be some conflict between the latest 11.2.1 and TT.
Any suggestions beside going to H&R tax software?
THanks
Don
So what solution do we have besides hoping the Apple or Intuit will fix the major problem with TT on IMacs for all users and taxpayers! It sounds like a 64 bit issue???
I tried HR but do not like their confusing instructions and policy of no refunds for their errors, or promises to fix the problems.
I will try to see if I Can get HR to work, but so far I disliked their installation process.
Purchased HR and loaded on to my iMac running IOS Big Sur 11.2.1 and appears to be OK so far.
Not sure that it downloaded all the data from the TT 2019 file, but better the the
present TT FU!
Cannot believe that neither Apple nor TT are not developing a fix for TT.
same or similar issue for me. I migrated my files and data from an older MacBook Pro running Mac Mojave (OS 10.14)
to my new 2020 MacBook Air--which is the Apple processor version and running Mac OS 11.2. TurboTax will launch once
Rosetta is installed but I can't create new or open an existing TurboTax 2020 files...
1st time ever posting.
I also was having TT2020 loading problems from CD. Did everything .... dragged to Applications, etc. Wouldn’t open. Trashed TT2020 and started over. Also saw probs people were having w/TT2019. I opened, updated as required, relaunched from launchpad ... all fine. Then saw TT2020 icon on Launchpad, opened and TT2020 opened fine. Will keep fingers X’d I can finish taxes....
Congratulations..... what version of Operating System are running? I have 11.2.3!
My TT2019 did run the previous year with older version and I filed with IRS and CA, but will not with 11.2.3.
Not sure where the issue is.
Don
MacOS Big Sur 11.2.3
My TT2019 would not run until I did the required TT19 software update, which I was prompted to do today. 2019 was the 1st yr I did taxes on Apple v Microsoft. It was seamless last year but definitely frustrated me this year. Not sure if Apple or Intuit issue....
Good luck
I have a 2020 iMac with Catalina 10.15.7 and 2020 TurboTax Premium will not load for me either.
Yes, thinking of bailing too.
I've pretty much given up. I did the federal by hand old school and I'm working on the state. I figure I'll have them both ready to go via snail mail in case this doesn't get fixed by April.
TurboTax 2020 won’t work on my imac
just spent 2 hours with TurboTax Support with same result. Tried download version on MacBook Pro 2019 running BigSur 11.2.1. Cannot get TurboTax to open on older MacBook running High Sierra 10.13.6 either.
Turbotax 2020 won't load
