It's immediately slow, and all the time. Even after a fresh restart of the whole computer. I noticed it was unusable garbage after one minute of use. You cannot expect us to believe you thoroughly tested this cr@p before you sent it out the door and didn't notice the issue.

Same issue here, beach ball every time and InDesign always not responding in activity monitor. Not usable at all, I will go back to previous version as soon as possible.

MacBook Air M2 16MB

InDesign 20.0.0.95

This is my tragic experience recorded, spinning wheel most of the time, almost any operation causes this 5 second delay. I simply cannot use this app for my daily work. The problem occurs even with empty documents!
As soon as I finish one project started in CC2025, I will uninstall this version.

What I experienced so far (on a 2018 MacMini with Sequoia): When starting fresh, Indesign 2025 works fine... until something happens - I bet something related to memory usage. For example this can be reproduced every time: when I open a book around 400 pages long and scrolling down on it, at some point the scrolling freezes and after that the beachball appears after every couple of moves - even after I close the file and browsing only thru the Indesign's Preferences. Quiting and restarting Indesign helps... until I guess some cache or buffer becomes full and after that it's beachball-time again...

Okay, here is some more detail on this problem.
- Beachballing happens upon opening a document
- Beachballing happens when you scroll from page to page or spread to spread
- Beachballing happens on EVERY click of the mouse, selection or drag. It happens on all boxes: Text or picture
- Blinking or screen voiding happens randomly when selecting any box or selecting a line of text. Especially picture boxes or text boxes with tables.
- Beachballing happens upon opening the INDD program in the home screen-before even opening a document.
- Beachballing happens when closing a document. It beachballs then goes to a blank progress bar that progresses slightly then disappears.
- After closing and returning to the Home screen it beachballs again, albeit briefly.

I have checked the system and it is running satisfactory. INDD 20.0 is the only app thus far on my 3 machines reacting this way.

All machines running Sequoia 15.0.1

Just was trying to replicate it, and it doesn't seem to be happening anymore - so I think it is fixed? yeah! (but in case you need the info: Sequoia 15.0.1 / on older documents created in Indesign 2024 / it was happening when trying to scroll through the document and also when I would double click on text to edit it) Thank you!

IOS 15.0.1 (24A348) tutti! subito

It's all documents no matter what the size or legacy. Older documents I save to INDD 20.0 right away but even this doesn't help. The slowness happens from the beginning of opening the document. As the program is used the slowness/beachballing on every action seems to get worse until it levels off at it happens with every click or even just the movement of the mouse.

As stated in my previous comment both machines are running Mac OS Sequoia 15.0.1
I don't use INDD much on my M2 laptop but will test it this afternoon - also running Mac OS Sequoia 15.0.1.

Agree, updated to InDesign 20.0 and immediately very, very slow, laggy and buggy. Previous version was snappy with no real issues. I'm talking ball of death after every action, even scrolling or zooming causes stuttering, screen issues with mouse size jumping from big to small, boxes not loading (similar to the pink screen error from a few years ago where the whole design will look blank as you pan around but if you draw a coloured box over the whole thing then delete it, you can see your design again). I also lost custom shortcuts to some but not all menu commands (for example I set one for duplicate spread in place and that disappeared but other shortcuts I had set AFTER that, saved to the same set still worked, I can't even guess why this would be). Also every time I click into an image box and go to resize the image constrain proportions lock turns off again. Previously if I lock it, on one image, it'd stay locked for all images until I unlocked it again. Now, even for the same image it turns back off if I click out then back into the image and go to resize some more. WHY WHYYYYYY.

(I'm on a Mac Studio M1 Max 64GB Ram on Sequoia 15.0.1)

Beachball **** with Indesign 2025. Slow opening, slow cut, slow copy, slow paste. I didn't find anything else wrong because before going any further I deleted 2025 and good thing I saved 2024 which opens a large file in 8 seconds, copy pastes nearly instantly.

This has also happened to me with Indesign 2025. It happens on the following machines:
- Mac mini: i7 Intel - 32 Gig RAM, 3.2GHz, 6-Core
- Mac mini: M1 Apple - 16 Gig RAM,
Both machines running Sequoia 15.0.1

Yes, this is the slowest version ever. Spinning wheel for a couple a second after each operation. This is absurd.

Same, terrible lag on my 2021 Macbook M1 Pro 16 gb. I did turn off Preflight, which helped a good bit but the lag is still there. Unfortunately, there's no default to turn Preflight off, you have to remember to do it for every opened file. I think I'm about to revert back to the previous version as well.

Agreed. It literally takes two seconds now to begin to select text, or to switch from one tool to another. I'm using an iMac with 32 GB of RAM and a i9 processor. This version of InDesign is hot garbage.

Updated to inDesign 2025. Using a MacBook pro M1 16gb.
The software is so laggy that I have to revert to the previous version.
Also tried the beta version as I was hoping, it won't have the same result, but it did. When I reverted to previous version, the problem went away.

Downloaded the new Indesign 2025 and noticed that it is delaying every time I go to select text or scroll to a different page.

Last update Indesig 25 slowed down a lot. Slow scrolling and typing correspondence between keyboard and software response. Very bad!
