Intel-Based Apps Will Stop Working in macOS 28

Yes, we know we’re still on macOS 26. In 2025, Apple announced macOS 27 would be the last version to support Rosetta for most Intel-based apps. (Beyond that, Apple will maintain a subset of Rosetta functionality for older, unmaintained gaming titles.) This fact has become relevant because in the just-released macOS 26.4, when you launch apps that rely on Rosetta for Intel compatibility, macOS may start warning you that they won’t open in a future version of macOS. These warnings are just reminders—nothing will change until you upgrade to macOS 28, probably in late 2027 or 2028, giving you plenty of time to find replacements. To identify Intel-based apps now, open System Information from the Utilities folder in your Applications folder, select Applications in the sidebar, and click the Kind column header to sort all your Intel apps together. iMazing’s free Silicon app does the same thing with a nicer interface.

  • I have been hosting phone bank parties for Bernie Sanders at my house as we head into the first caucuses and primaries. It is fun talking to folks out in Iowa and now New Hampshire to see who they are supporting and to tell them about the Senator from Vermont. I like being involved and feel if you are not involved, informed and voting you do sacrifice your right to complain about the results.

  • _Hello Friends,_

    The big winter storm called Jonas is heading for the east coast and Vermonters are hoping that it tracks north of the current projections but it looks like it might miss northern New England and hit the coastal areas. The lack of snow in Vermont and the unusually high temperatures have hit the Vermont ski areas and local merchants pretty hard. Here it is the end of January and no significant snow in Vermont. Well for all the skiers and especially for the businesses I hope that those areas that can’t really handle snow get bypassed and Vermont gets the big dump because Vermonters are ready.

    Down here in Key West it has been sort of cool meaning I have to wear long pants and shoes, although if it was this warm in Vermont everyone would be in shorts. Down here when it gets below 65 you see people with down coats. NOAA reported this week that 2015 was the warmest year in recorded history breaking the record from 2014 by far.

    Apple honored Dr. Martin Luther King, Jr. on its home page on the national holiday on Monday with Dr. King’s quotation “Life’s most persistent and urgent questions is, What are you doing for others”.

    We always advertise our “Celebrate Diversity” slogan during this time of the year. We strongly feel that you gain strength through diversity whether it is race, religion, national origin or sexual orientation. I remember a long time ago we had a series of Celebrate Diversity web banners that created a lot of controversy with some sites refusing to run them. Diversity is much more mainstream now despite some candidates for President attempting to divide us.
