Have expensive MAC PRO running 10.15.7 and would like to update to 13.5.2. Why can't I find this on the very lucrative Apple site?

Hi vaultstudio,

welcome to the Apple (user-to-user) Community.

Re: "MAC PRO running 10.15.7 and would like to update to 13.5.2"

To check whether the Mac OS version that you want to run is compatible with your Mac Pro model:

You may want to view Apple support's article: Identify your Mac Pro model - Apple Support

which lists the newest available MacOS for each model.

Re: 13.5.2: What's new in the updates for macOS Ventura - Apple Support

says the newest available version is macOS Ventura 13.6.2

Seems the two Mac Pro models below are compatible:

• Mac Pro (2023)
• Mac Pro (2019). (From: macOS Ventura is compatible with these computers - Apple Support)

"Apple Support" generally supports Apple customers with a knowledge base, and contact options.

Although there is an article with info. on obtaining earlier versions than the one currently available, I do not know whether the links / servers for obtaining earlier Mac OS versions are working currently / still up-to-date.

Links to earlier Mac OS versions: How to download and install macOS - Apple Support

It is likely you may need to upgrade gradually from MacOS 10.5.7 ... ie: in gradual steps thru to the higher versions.

Please let the community know if you still need help obtaining / installing the desired MacOS version.

or

Support (online chat / phone/ email etc.) may be available from the link at the bottom of the website below:

All the best :-)

You can't find macOS 15.5.2 because there is no such version of macOS.

The latest version of macOS is Sonoma – 14.*. Until Sonoma's successor arrives (probably late next year), there won't be a macOS 15.0, let alone a macOS 15.5.2.

If you haven't already tried : you might want to see if following the tips in the article: How to download macOS - Apple Support work for you, to upgrade gradually from OS 10.15.7 to 13.5.2

The people who are answering your questions here are NOT Apple employees. They are other users, who Volunteer their time and energy to help you in whatever way they can.

Sometimes you might get information that is tangential to you wanted to know, or WAY more information than you wanted.

PLEASE try to be gracious in your responses. If you got more than you wanted to hear, do not assault the person who gave you tangential or ‘too much' information. Instead, understand that they were TRYING to be helpful, even if their answer did not line up perfectly with your query.

Just ignore the overage and get on with solving your problems, and count your blessings that someone was willing to help, even if the answer was "too much" or “way off base”.

If your important parts of your question did not get answered, just ask a more pointed question and Readers will try again.
