I use Appcleaner all the the time so that might not be the problem. Publisher is using between 78-89 GB (virtual) Ram in my project. It is a book of about 150 pages and 1145 tiff pictures of about 85 mb each. Loading takes about 15 minutes and I really have to be patient to do any changes. So, I tell you what I did. I reinstalled Publisher AND Cleanmymac. Cleanmymac warns me of ram usage and clears it on my request. So, in fact Cleanmymac is helping me now to carry on working. All this started after the upgrade to Big Sur anyway and my impression now is that Publisher 1.8.6. needs a serious update. I use Final Cut Pro as well for a 6k video and there are no problems whatsoever. I have more 'heavy' programs and everything is fine, it is Publisher only giving these problems. I hope that Affinity will come with an update soon.

Well, problem is not solved. I use the max workspace and I get warnings about reaching the maximum and the Publisher stops completely. Forced stop is the only option then. I can not use Publisher anymore. My Macbook is 16 GB Ram and maybe that is the problem. I have no idea what to do. I am considering buying a Mac Mini 64 GB Ram or is the new Mac Mini M1 (but then still 16 GB) an alternative? I read about the speed and graphic possibilities of the M1. Update: Macbook pro crashes because memory usage Publisher goes over the top. Finder tells me usage is 79 GB and the crash report.. It is only happening with Publisher. I added some pictures.

Problem solved. I deleted CleanmyMac and reinstalled Publisher, restarted the laptop and had a glass of wine and Publisher produced a full PDF, thank you thomaso for your advice.

I exported the PDF files in parts. The book has 120 pages. Exporting page 1-60 (CMYK/8 bits Coated Fogra 39, PDF/X-1a:2003 ) no problem. Exporting 60-120 did not work, stopped half way and stopped Publisher as well (forced quit after one hour). Then, exporting separately page 60-90 and 90-120 no problems. CleanMyMac gave the warning of apps memory 81 GB several times on exporting 60-120. Publisher 1.8.6. Also loading the book file takes about 20-25 minutes for 120 pages and that was never that long because this book is based on another Indesign IDML (and now Apub file) version and worked fine two months ago. I have Indesign for a couple of days left (after 15 years) and there are no problems using Indesign. 1TB HD has 615 MB left so that is not the problem. I checked the tiff files and I do not see any corrupt files as far as I can see that. I can open them In Affinity Photo, DXO and Luminar 4.

Thank you for the replies, I will try it out and let you know as soon as I can. To keep you busy I will post my 2021 card in (double) Dutch and wish you all an excellent creative year.

It looks like Big Sur is the problem but it could be something else as well. I use the i7, 16GB Ram and 1TB HD Macbook Pro (2019) and the latest version of Publisher. Publisher will only close after a forced stop I am working on a photo book including 824 High resolution tiff pictures up to about 80 mb each. I cannot make a PDF because the ram is finished after 25% of writing the file. It must be a huge pdf file with all these pictures (or not). There is a deadline coming up before it goes to the printer. I even thought of buying the M1 Mac Mini but the only difference is the M1 instead of the i7. M1 seems to be better with graphics. Any advice is welcome and btw......al the best for 2021 and hopefully there will be some light behind the dark horizon for us all.
