New error He now suffers from the latest MacBook Air (with M4), and some people find themselves unable to install the latest MacOS 15.4 filter.

Apple Macbooks is famous for its reliable performance and a very small amount of errors in general. However, some people who vibrate the new MacBook Air are now suffering from a strange problem that prevents them from updating their devices. the Apple fans are frustrated to Reddit to find solutions while trying to install the MacOS 15.4 filter to no avail.

Users affected are welcomed by an unavailable error message stating: “MacOS cannot be downloaded. Ensure that you are connected to the Internet and try again, or connect to Apple support for help.”

Moreover, the problem also appears to affect M4 Max and M3 Ultra Mac Studio users, who report the same error message when trying to download and install the update.

According to what was reported, Apple appears to be wrong because of the inconvenience. Apparently, the technology giant has not provided the Cuertino technology key to the appropriate decoder for the M4 MacBook Air to be able to install the update.

Yes, Apple encrypts software updates and a recklessly disassembled key so that your device can install the new program. It seems that the KEWAN Master of the New Business Administration is not available from Apple servers at the present time, and therefore, the update cannot be installed.

Unfortunately, though, there is no solution to this issue today. If the new MacBook Air is running the program that came with it upon arrival, you will not be able to update to the MacOS Sequoia 15.4 candidate. Well, you will do so, but initially Apple needs to fix the problem at the end of it to be able to install it.

MacBook Air M4S MacOS 15.4 Beta 4, however, is not affected. Therefore, if your device is running the Beta update, you should be able to install RC as well. Also, it seems that the oldest MacBook Air models are not affected by the current situation.

If you are wondering how the version (or RC) is different from the beta version, well, RC is a semi -final version of the program, and it is expected to have fewer errors from the public beta version. Candidates usually come with all the new features that the official update will achieve. Currently, though, users will have to try to wait until Cupertino fixes the error so that they can update the Master of Business Administration.
