I hope you are doing well, and we apologise for the trouble you had with the app.
Please ensure you have the latest version of Acrobat installed on the machine: 25.001.20458 Planned update, Apr 15, 2025. Check for any pending updates from the Menu > help > check for updates, install the updates, restart the app and the machine, and check. For more information, see this: https://adobe.ly/42n8HLl
If the app still freezes with the latest build, please collect the logs from the affected machine and share them with us for further investigation.
Sorry for the inconvinience caused at your end. Can you please help me with the following details so that we can triage the issue better ;
Once the Acrobat Hangs again I will be needing the Spindump and Smaple Process for that hang state. Pleae make sure to take dumps and sample process at the time when acrobat is in hanged state. You will be able to find both these in the activity monitor after clicking on the Acrobat process and then click on Settings icon on top bar in activity monitor.
I had the same issue. When I went into Activity Monitor, I noticed that the "Adobe Acrobat Synchronizer" process was also not responding. I killed that process, and this issue went away. (It immediately relaunched itself and appears to be functioning without any issues.)
It seems like Acrobat makes some sort of (blocking) callout to the Synchronizer process, so if that process has frozen, Acrobat will freeze too.
If it happens again, I'll try to get a process sample from it. But I don't need or use the Synchronizer functionality, and killing it did indeed solve my immediate problem.
Thanks so much Wisq... that helped me to get functional on my end again. I have been troubleshooting this issue (getting Acrobat to work) for the last couple of hours to no avail, and killing the "Adobat Acrobat Synchronizer" really helped.
Im having the same issue and this was a great temporary fix. Im on 10.15.4 - 2018 MBP 15" 16GB RAM. Adobe Acrobat Pro DC 2020.006.20042 - Ill keep looking for a more permanent fix but this at least keeps it moving. Thank you!
I hope you are doing well, and thanks for reaching out. Could you please share more details about your issue? Have you tried the suggestions shared in this thread? If not, please try once, and let us know how it goes.
I guess I just have no idea what you're all talking about. What's happening to me is that my 'updated' version of everything just takes FOREVER to load up, save, etc. I tried looking at the adobe acrobat synchronizer and there wasn't anything there and/or if I did find something that looked similar, there were so many things running under it that my mind went numb.
I'm running Acrobat Pro 2020 for Mac on OS 11.4. It's not a subscription version. Acrobat hangs when I try to Save or Save As... I have 68 "Recent hangs". Attached are the tests you requested.
Thanks very much for your help and I'm very willing to provide more information.
Acrobat is totally greyed out and inert when it hangs. Nothing responds. I have to force-quit to shut it down.
So this sounds promising but I have no idea what "Spindump" and "Smaple Process" mean. Could you please explain those terms and give step-by-step examples of them?
What is the version of the OS and the Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the recent version 24.02.20736 installed. Go to Help > Check for updates and reboot the computer once.
Also try to repair the installation from the help menu (Win Only) and see if that works.
You may also try to create a new test user profile with full admin rights in Win or enable the root account in MAC and try using the application there and check.

Having the same issue. Acrobat DC totally unusable. Hangs even opening a simple 1MB file. Tested Preview and 'bang' opened in a second! How do I fix it? Mac OS 10.15.7
This issue has been ongoing and getting worse. I have called Adobe for help, only to be told that the problem lies with the document and not the program. However, I do not and have not experienced these problems with other pdf programs. This problem has become so intolerable that I have resorted to using Google Chrome for opening up and reviewing pdf documents. This is really pathetic and confirms that Adobe either (1) could care less about the quality of its program or (2) that the people responsible for maintaining and running Adobe are incompetent. If anyone has any suggestions about better alternatives than using this problem, please post them.

I too am having the same issue. Onto a brnat new MacBook Pro M1 chip machine and still haveing the same lock up as the old MacBook. Come on Adobe???? You seriously need to figurte this out!! I cant do my daily work.
We are extremly sorry that you are facing this issue. We are unable to reproduce the issue in-house. Can you please share the spin dumps and sample process when the Acrobat/Reader goes in a non responding state so that we can investigate it further.
A similar issue is happening for me. Every time I try to save a document after editing it freezes and I have to kill the program and my document doesnt save. What can I do?
Agreed.. Acrobat Pro 2020 Mac and System 11.2.2... everytime the app freezes when a document is edited, both when saving and if I try to email from Acrobat as well.. two visits to Customer Support have done NOTHING!!!
I'm having the same problem...Acrobat Pro 2020 running on a Mac mini (M1, 2020) with Big Sur 11.2.3. Mine will usually work for 5-10 minutes and then freezes. I've reinstalled Acrobat and run all updates with no luck. Adobe, please help!
What is a spin dump and what is a sample process? You've got to write in user-friendly language if you want the information to be able to help us fix your problem on our computers.

I decided to dump Adobe Acrobat on all my Macs and took the time to learn a bit about Apple "Preview"! It works fine and I can sign and annotate my docs with a bit more work. I must say that my Macs run flawlessly now. Bye bye Adobe! Sad you have not focused more on the Apple community. Clearly you have given up or these issues would not persist.
What is the status on this issue? I have the exact same issue that came out of nowhere for the past 2 weeks and now Adobe Acrobat DC Pro is literally unusable.
I may have found the solution! Adobe just change the way sign in works just recently (something regarding personal/bussness profiles) so I logged out of creative cloud app and then back in. Acrobat is not locking after startup anymore.
