How To Update Macos High Sierra 10136 To 1015 -

Important Note: The version number you provided (10.13.6) is the final release of High Sierra. There is no version 10.13.136. This guide assumes you meant updating from macOS High Sierra 10.13.6 to macOS Catalina 10.15.x (the immediate successor to Mojave, as High Sierra cannot directly jump to newer OS versions like Ventura or Sonoma on most older hardware).

Bridging the Gap: Updating from macOS High Sierra 10.13.6 to macOS Catalina 10.15

The evolution of Apple’s macOS is marked by significant interface and architectural changes. For users still running macOS High Sierra (version 10.13.6), the leap to macOS Catalina (version 10.15) is not a minor patch but a substantial upgrade. While High Sierra refined the file system and focused on stability, Catalina fundamentally altered the operating system by removing legacy support and introducing new core applications. However, before beginning the update process, users must recognize that this transition requires careful preparation, compatibility checks, and an understanding of what will be lost.

Step 7: Can’t or Don’t Want Catalina? Consider macOS Mojave (10.14)

If you need 32-bit app support, do not upgrade to Catalina. Instead, upgrade to macOS Mojave (10.14) – the last macOS to support 32-bit apps. how to update macos high sierra 10136 to 1015

To get Mojave:

Search App Store for “macOS Mojave” or use Apple’s download page. Same process as above, but Mojave is version 10.14.

Mojave still runs most High Sierra apps and introduces Dark Mode and Dynamic Desktop. Important Note: The version number you provided (10

Note: Mojave is also no longer receiving security updates (except critical ones for some users). For maximum security, if your Mac supports it, go to macOS Big Sur (11) or Monterey (12). But from High Sierra, you may need to go to Catalina first.

Method 1: Direct App Store Link (Recommended)

Open App Store on your Mac (or click Apple Logo → App Store…).
Search for “macOS Catalina.”
Look for the result that says “Get” or “Download” (not “Open”).
If you see “View in Mac App Store,” click that and then click Get.

3. Fix Disk Permissions & Rebuild Spotlight

Open Disk Utility > select your startup volume > click First Aid > Run. This fixes any permission or directory issues from the upgrade.
Go to System Preferences > Spotlight > Privacy tab. Drag your main hard drive into the list, then remove it. This forces Spotlight to reindex.

Conclusion: Is the Upgrade Worth It?

Updating from macOS High Sierra 10.13.6 to Catalina 10.15 is less about getting new features (like Screen Time or Reminders upgrades) and more about maintaining security and app support. While Catalina receives security updates (until late 2022, now obsolete), High Sierra is unsupported. However, the loss of 32-bit apps is a major trade-off. If your essential software is 64-bit and your Mac is from 2012 or later, the update is logical. If you rely on legacy software, consider staying on High Sierra or jumping to a middle ground like macOS Mojave (10.14) , which still supports 32-bit apps. Always remember: a complete backup before any OS upgrade is your safety net. Proceed with knowledge, not just enthusiasm.

Here’s a step-by-step guide to update from macOS High Sierra 10.13.6 (the final version of 10.13) to macOS Catalina 10.15.

Important notes before you start:

Your Mac must be compatible with Catalina. Supported models include:

MacBook (Early 2015 or newer)

MacBook Air (Mid 2012 or newer)

MacBook Pro (Mid 2012 or newer)

Mac mini (Late 2012 or newer)

iMac (Late 2012 or newer)

iMac Pro (2017 or newer)

Mac Pro (Late 2013 or newer)

Catalina drops support for 32-bit apps. Check your apps first:
Apple menu > About This Mac > System Report > Software > Applications – look for “64-bit (Intel): No”.

Back up your Mac using Time Machine before upgrading.

If you actually want 10.14 Mojave instead of 10.15:

Search the App Store for “macOS Mojave”.
Download and run Install macOS Mojave (same steps as above).
