Apple has released macOS Tahoe 26 as the latest major update for Mac. The update introduces a refreshed design, gaming improvements with Metal 4, and better app performance on Apple silicon. While the upgrade is working smoothly for most users, others have reported problems ranging from failed installations to faster battery drain.
Like with every new macOS version, these issues are common in the first weeks and are usually resolved by Apple in follow-up updates. In the meantime, many of them can be fixed with simple steps. Here are the most common macOS Tahoe problems and how to address them.
Installation issues
Some users have reported stuck progress bars, failed downloads, or errors when installing Tahoe. Apple recommends ensuring at least 20 GB of free space before starting the upgrade. Trying the installation in Safe Mode or using macOS Recovery to reinstall can also help.
If you prefer to start fresh, follow our guide to clean install macOS Tahoe 26. You can also create a macOS Tahoe bootable USB installer to make the process easier. If the Mac App Store isn’t working, you can download macOS Tahoe without the Mac App Store and install it manually.
Compatibility note: macOS Tahoe supports all Apple silicon Macs and a limited set of Intel models:
- MacBook Pro (16-inch, 2019)
- MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports)
- iMac (27-inch, 2020, Retina 5K)
- Mac Pro (2019)
Older Intel Macs remain on macOS Sequoia. Tahoe is also expected to be the final macOS release for Intel.
Slow performance
After upgrading, some users notice slower app launches or lag. This is usually due to Spotlight and other background processes reindexing data. Performance often improves after 24–48 hours. If problems continue, restarting in Safe Mode and checking login items may help.
App compatibility
Apps that use system extensions, audio plug-ins, or virtualization may not work correctly after the update. Developers are gradually releasing Tahoe-compatible versions, so checking for updates is the best solution.
Wi-Fi and Bluetooth issues
Intermittent Wi-Fi drops and Bluetooth devices failing to reconnect after sleep have been reported. Resetting network preferences, forgetting and re-adding devices, or creating a new network location in System Settings usually fixes the problem.
Battery drain
MacBook users have noticed shorter battery life after updating. Background indexing can increase power usage for the first few days. If the issue continues, checking Activity Monitor for apps using high energy and adjusting power settings can help.
External display problems
Some users with external monitors report resolution errors or displays not waking from sleep. Manually adjusting display settings or reconnecting the monitor usually works as a temporary fix until Apple releases an update.
Spotlight search
Spotlight may fail to show new or updated results. Rebuilding the index often fixes this. Go to System Settings > Siri & Spotlight > Spotlight Privacy, add your main drive, then remove it to trigger a reindex.
These are the most common macOS Tahoe issues so far. Apple is expected to fix many of them in upcoming point releases, so it is important to keep your system updated. In most cases, basic troubleshooting can resolve the problems without waiting for an official patch.
FAQ
Is macOS Tahoe supported on Intel Macs?
Yes, but only on a few models: the 16-inch MacBook Pro (2019), the 13-inch MacBook Pro (2020, Four Thunderbolt 3 ports), the 27-inch iMac (2020), and the Mac Pro (2019). All other Intel Macs remain on macOS Sequoia.
Why is my MacBook battery draining faster after updating?
macOS Tahoe performs background tasks such as Spotlight reindexing and Photos analysis after installation. These can temporarily reduce battery life. The issue usually improves after a few days, but checking Activity Monitor for apps with high energy usage can help identify other causes.
Will Apple release fixes for these issues?
Yes. Apple typically rolls out point updates (such as macOS 26.0.1) within weeks of the initial release to address bugs and performance problems. Keeping your Mac updated is the best way to ensure you receive these fixes.
What can I do if my apps stop working?
Most compatibility issues come from older apps not yet updated for Tahoe. Check the developer’s website or the Mac App Store for updates. If the app is essential, you may need to temporarily use an older Mac running Sequoia until an update is available.
