Is High Sierra compatible with Quicken 2007?

Yes, I did. I installed an SSD external drive and tried putting my backup files on that as suggested by another poster. Quicken didn't backup properly. I even purchased Quicken 2018 an imported for Quicken 2007 data. For the most part, it imported OK there were four investments that imported incorrectly. I asked Quicken for a refund.

I'm not sure what to do now. I don't like having a decent backup.

I actually do not use Time Machine. I use Carbonite as well as an external hard drive. I don't believe Carbonite gives me Quicken file backups I can retrieve in full - - I've tried that before.

I have shut off the automatic backups because it seemed to be replacing my file copies with empty folders. (I have many Quicken files that I work with.)

Really not sure what to do here going forward. Can I uninstall High Sierra?

I don't think I can do that with Carbonite but I will check.

I'm just on the line with Apple who is checking but says I may have to wipe my whole computer to reinstall Sierra. That would create problems as well.

I don't want to back up anything to my external hard drive since installing High Sierra. What a pain!!

Since your haven't backed up to your external hard drive since installing High Sierra, your Quicken files should be intact. The only question is see is how to re-install Sierra. Maybe Apple support can help you through this. I installed High Sierra twice and had to reinstall Sierra twice. My Quicken files are intact and working well.

Quicken 2007 is 32 bit and the newer MacOS are 64 bit. The problem is that High Sierra, instead of using the extended journal disc format HFS extended, uses something call APFS. APFS will not allow Quicken 2007 to write backup files. The folders are empty.

Unless the Quicken data file is on a volume formatted OSX Extended (journaled) Quicken will not automatically backup its data file. Put the data file on a volume formatted OSX Extended (journaled) it it will backup as advertised.

Are you sure? I purchased a 512GB External SSD drive and formatted it as OSX Extended. I then selected the SSD as the destination for the backup. It still failed to backup

Any Ideas what I could have done wrong? Quicken 2007 was residing on the newly formatted APFS.

I'm not sure I totally understand what you are suggesting.

Are you saying to move my original Quicken files onto my external HD and instruct the backups to go there as well? Wouldn't that mean I'd have to work off of the external HD all the time? I bring my laptop with me on the road and work on different clients' files. That would be a hassle to drag the external HD with me all the time.

Hum? Where do you think the data file resides on Mac HD? I don't see it in Applications but there seems to be such a file in Documents. On my second attempt to resolve the problem, I moved the file in Documents to the SSD drive and that didn't work. I'm wondering if I should remove all Quicken 2007 from Mac HD and reinstall on the SSD. When I open from that location it might put the date on the SSD. Any thoughts about where to find the proper file on Mac HD?

This is what "Old Toad" has suggested, I've yet to make it work but I'm trying. The SSD I purchased is about the size of a box of tic tacs and has a short USB 3.0 cable. I trust SSDs more than conventional HDs because there are no moving parts to fail.

What I've found out thru experimentation is that if the Quicken data file is on a volume formatted APFS it won't automatically run it's backup routine. If it's on an HFS+ volume you can have the backup file saved anywhere you'd like, even an APFS volume.

Here's my problem. I purchase a 512GB SSD drive and formatted it to HFS+. I then directed Quicken 2007 to backup to that drive, it failed.

I thought about partioning my Mac HD but I'm not willing to do that just yet.

Any thoughts why this isn't working?

I upgraded to High Sierra before checking with the Mac community using Quicken 2007. I didn't have any problem with Sierra so I wasn't thinking. After not being able to back up my Quicken data file I logged on and saw your reply. I formatted a flash drive to Mac OS Extended (Journaled) just like you suggested. Mac OS X Extended (Journaled) was not an option in my Disk Utility. I copied Quicken to the external drive and it gave me an error message that it could not open it. If I keep my Quicken open I have had no problem with losing any transactions but I'm afraid not to have a current backup. Any suggestions?

I purchased Quicken 2018. It has an entirely different feel. Furthermore, Quicken 2018 failed ot correctly import my mutual fund transactions. The balances were correct but each investment was doubled and the re-investments where shown but not computed. I demanded my money back. Quicken 2018 is not ready for prime time.

Quicken 2007 is a great program and very functional. In my opinion, in an attempt to build a better program, they've dumbed it down.

I am running Quicken 2018 on my High Sierra 10.13.2 installation without issues. I find it superior in every way to Q2007, something I used for almost ten years and finally made the break.

There is one thing you need to know about Quicken 2018 though. You can no longer buy the product outright. Quicken has moved to a subscription model like Microsoft’s Office 365 in which you pay a yearly fee to get the latest updates and online services. Some will find that unacceptable but Quicken states that if you fail to renew your subscription the app will still work, you just won’t get support, online services, or updates.

Look, eventually Q2007 will stop working on macOS. Quicken no longer supports it and Apple certainly won’t be looking to make sure a 10 year old unsupported app still works. So you will have a basic decision to make. Do you freeze your computer at a point in time so Q2007 will still work or do you move forward?
