How to Open a BitLocker Drive on Mac
A BitLocker drive from work or school will not open on your Mac. DiskBee ships a BitLocker engine that unlocks it with a password or the 48-digit recovery key, then lets you read and write normally.
External Drive or USB Stick Not Showing Up on Mac? 5 Causes and Fixes
External hard drive or USB flash drive not showing up on your Mac? Work through five common causes in order: cable and port, mount state, file system, power supply, and hardware failure. Each section ends with what to try.
Four Ways to Write NTFS Drives on Mac, Compared
A Mac reads NTFS but will not write to it. The workarounds are dedicated NTFS software, reformatting to exFAT, Apple's hidden write switch, or a Windows virtual machine. Here is what each one costs you.
NTFS, exFAT or APFS for a Drive Shared Between Mac and Windows?
NTFS is the sturdiest option on Windows but read-only on macOS. exFAT works on both and has no journaling. APFS is Mac-only. Here is how to choose for an external drive.
How to Make a Mac Write to NTFS Without Reformatting
An external drive full of files cannot be reformatted just to get write access. Here is the installation that gives macOS write support for NTFS, with every existing file left in place.
Using NTFS Media Drives on a Mac: Notes for Photographers and Editors
On-set media drives and client delivery disks usually arrive formatted NTFS, while the editing happens on a Mac. Here is how to work from those drives directly instead of copying everything first.
One External Drive, Two Systems: Mac and Windows
The same external drive can move between Mac and Windows without friction. Choose the file system once, set up the Mac side, then keep two unplugging habits.
Testing External Drive Speed on a Mac, and Reading the Result
macOS includes no disk benchmark. Here is how to measure an external SSD or USB stick properly, which four numbers matter, and what a suspiciously low figure usually means.
Why Disk Speed Test Results Vary Between Runs
Same drive, same Mac, different numbers every time. A swing of 10 to 15% between runs is normal. Here are the five factors behind it, how to test properly, and which changes deserve attention.
Formatting a Drive as NTFS on a Mac, Where Disk Utility Stops Short
Disk Utility lists APFS, HFS+, FAT32 and exFAT, with no NTFS entry. Four ways to end up with an NTFS volume anyway, plus volume naming rules and a check you can run on a Windows PC afterwards.
Checking and Repairing an NTFS Drive on a Mac, Without First Aid
First Aid has no NTFS code path, so it cannot check or repair those volumes. What actually goes wrong with NTFS on Mac, why ntfsfix is not a substitute for chkdsk, and what a four-level read-only check can settle.
Why an NTFS Drive Mounts Read-Only on a Mac
Files open, nothing copies on. That is macOS mounting NTFS read-only, not a drive on its way out. How to confirm the cause, what the zero-cost options actually give you, and how to pick a driver that survives the next system update.
Why DiskBee Needs macOS 15.4, and What Older Macs Can Still Do
FSKit arrived in macOS 15.4. DiskBee is built on it, which is why the installer asks for that version and why the driver needs no kernel extension. Here is the trade-off, and the honest options for a Mac that cannot get there.
