Support for Macbook pro 13 inch 2019 for Mac OS 26 Tahoe

At some point in the very distant future, it may become necessary for a Mac to be able to run something later than Tahoe to help restore / update an iPhone, or to do manual synchronization (e.g., of music) with an iPhone.

High Sierra is seven major versions behind Sequoia – but is theoretically sufficient to manage iPhones running the latest version of iOS, iOS 18. So if we make a conservative guess that Sequoia will be enough to manage iPhones running the next five versions of iOS, that would suggest that your Mac could eventually manage iPhones running iOS 30. Maybe even a little beyond that.

In any case, iPhones get app updates directly from the App Store, so even if you had a Mac that was too old to be able to restore your iPhone or load music onto your iPhone, that wouldn't keep your iPhone from updating its apps.

I have a Macbook pro 13 inch 2019, I know that this mac won't have support for MAC OS 26 Tahoe.

I want to know if this also will become a problem for updating my IOS apps in the Apple App Store?

No.

Update apps from the App Store on iPhone

you can see about compatibility here for your mac, independent of your iOS question:

macOS 26 is compatible with these devices

OS - macOS Tahoe 26 - Apple

It is quite possible that Apple will raise both the minimum system requirements for XCode, and the minimum version of XCode needed to publish apps in any of the App Stores. As to when they might do that to a degree that would keep you from using your current Mac as a primary build machine for App Store apps, your guess is as good as mine.

Sorry, but my question was not very clear.

The problem is not exactly about updating Mac Apps.

Is about using Xcode to publish an update to an iphone App in the Apple Store. In the past I needed to upgrade to Xcode 16 in order to be able to publish an update because apple did not accept updates with Xcode 15.

I suppose that eventually I won't be able to update xcode in this Mac therefore in the future I won't be able to publish updates to the app store.

And the only way to update an app would be to buy a newer mac.

App Store submissions require current Xcode.

If your question was whether the inability to upgrade beyond Sequoia was actually "Will this become a problem for updating my Mac apps?", the answer is "Yes."

Some vendors like Microsoft and Adobe have a policy of supporting only "the most recent three". At the moment, Sequoia is the most recent version of macOS, but when Apple releases macOS 28 in fall 2027, Sequoia will fall out of that list.

If you look at some of Apple's own applications, like Pages, Numbers, and Keynote, current versions now require one of the "most recent two." That might suggest that you could stop getting updates for those sooner – maybe even as early as the release of macOS 27 in fall 2026. (Also that you should grab whatever updates are available while you can grab them.)

Then there are applications like Firefox, LibreOffice, and the Affinity V2 applications (Photo, Designer, Publisher). These will run even on Catalina, which is five major versions behind Sequoia. So you might be able to run current future versions of them on Sequoia even after macOS 30 comes out in fall 2029. (No guarantees, but it would be surprising if any of these developers suddenly decided to support only the "most recent three".)
