Braun Phototechnik MultiMag SlideScan 4000 / 4000b.I know that we used to have some Forum users still using 4990 scanners.SilverFast 8.8 is macOS Catalina compatible for the following scanners: I could try Ken's approach, but I really didn't want to run a virtual Windows machine on my Mac just to use the scanner. Do any of you digital gurus out there know how all this fits together? Will the 64-bit version of Photoshop Elements automatically use the new driver even if I have no working Epson Scan software any more? But I was putting this off, because if it won't work with my scanner it is wasted money. So current status: I have an out-of-date (32-bit) version Photoshop Elements, I know I need to buy the new 64-bit version. To scan negatives and get them into Photoshop Elements, the Epson tech rep said I would have to call either Adobe or Apple.
There is no 64-bit Epson Scan or Epson Scan 2 software which will work with the old 4990 scanner.
Having spoken with Epson, it seems that I did successfully download their "ICA Scanner Driver v5.8.9 for Image Capture" which (a) they say is Apple software, not Epson's, and (b) is in the Image Capture app even though it does not show a new update date.
