Set permissions not only for the app bundle but for all files contained within (you may have done this but it's not clear from what's been said so far): Here are some other things you can try in addition to the answers already given.ġ. This is a known, not fully resolved problem with some apps, probably older apps which haven't been updated for Big Sur. Might take a while to get this one to soak in (at least for me), but clearly “Have you tried running it under Rosetta?” is another question we should ask ourselves/others when trying to diagnose issues on M1-based Macs. Have an M1 Mac? Now you have another troubleshooting step to try. That’s what first tipped me off that “Open Using Rosetta” might solve it, once I remembered that iTerm was running under Rosetta which means that lldb was running as an Intel process. Once it was ready, I typed run and it worked. Lldb ~/Library/Printers/Brother\ HL-2270DW\ series.app/Contents/MacOS/PrinterProxy One “Trick” that I used to help solve this… Pro-Tip: Get Suspicious Package and set it as the default app for all. I should also probably stop using my pkg installer shell script in iTerm (I might be able to use it in Terminal.app which I left to run as an Apple Silicon process). But the fact that I had to manually set the printer apps to run under Rosetta makes me at least wonder if that would have been true even if the Installer app had been running as an Apple Silicon process.Ĭonclusion: I should probably test that. It’s entirely possible that I could have installed this with the regular Installer.app and had the same experience. So chances are good that I installed the Brother drivers with that script.ĭoes that matter? I really have no idea. pkg that I need to install, I have a shell script that runs sudo /usr/sbin/installer with the proper parameters. Here’s the weird part: Lots of times when I run into a. I use iTerm as my default terminal app, and I have it set to always open using Rosetta, which was recommended for making brew work with Big Sur on M1 macs.Īs a result, anything that I do while using iTerm is done as if this is an Intel Mac. Now, that page only mentions compatibility with macOS 10.15, and I'm using Big Sur, but I guessed that it would work and probably just had not been updated for Big Sur yet because some companies take forever to do that. I didn't want that, so I went to the Brother website and found the official Brother Downloads page for the HL-2270DW. When I tried to install the printer, macOS was going to install it as a generic printer. Some further thoughts on how I got into this mess… Needed Official Drivers from Brother Setting these apps to “Open in Rosetta” immediately solved the issue.
