If you’re not sure what you should be patching or why, read my Patch Primer.

Apple Security Blossoms

Apple released a ton of updates this month. The latest Mac OS update requires over 11GB of space, always good to check your storage via Settings before trying to install a large update like this.

Apple fixed a Mac OS security hole that allowed hackers to steal login info known as ClickFix.

Apple released TWO updates this month for iOS and iPadOS. The latest fixed a problem Apple downplayed as database problem but instead this was the OS storing sensitive information from the Signal app long after it should have been deleted. More details on this security problem here.

Be aware that Apple (like Microsoft and other vendors) downplay the security angle to their updates regularly which fools users into thinking these updates are not important or only new features. A lot of folks distrust new features hence they don’t update when they should.

Adobe Acrobat

Adobe released security updates for its PDF product Acrobat and Reader plus all the other Creative Cloud Suite products April 14th.

Normally Adobe sends out notifications but if you’re not sure, go to Menu, Help and then Check for updates.

Details on the latest Adobe updates here.

ScanSnap Firmware

People often forget that devices like scanners and printers require their own updates.

Scansnap recently released firmware updates for their popular scanners. This firmware is a) security update and b) helps the scanner save to Scansnap Cloud storage for folks who use that feature.

Give a little updated love to your scanners and printers this month.

Microsoft Patch Tuesday April 2026

Microsoft released a whirlwind of Windows updates this month. Then released several emergency patches to fix the patches. Always a good idea to wait a few days to updates Windows. Always a good idea to make sure you have good backups.

Microsoft patched 165 security holes this month, the second largest patcharama ever. More details on this exhaustive Microsoft Patch Tuesday April 2026 here.

An ounce of patching is cheaper than a pound of hacking.
