millort_y Posted June 17, 2025 Share Posted June 17, 2025 Hey everyone, I’ve run into an issue and could really use some advice. I’m unable to unlock my seagate external hard drive on my Mac. The drive is a seagate one touch, 5tb Quote Link to comment https://www.insanelymac.com/forum/topic/361206-how-to-unlock-seagate-hard-drive-on-mac/ Share on other sites More sharing options...
PixelDreamer5 Posted June 17, 2025 Share Posted June 17, 2025 Hey, welcome to this forum When you say you can’t unlock your Seagate, do you mean you forgot the password or you’re just confused about where to type it? Quick tip - maybe your drive is APFS encrypted and the password prompt doesn’t pop up automatically. I had this happen to me too. Just unplug the drive and plug it back again and that usually brings up the unlock menu. If it still doesn’t appear, try openin the drive from Finder’s sidebar. And if you don’t even see it there, double-check Finder’s sidebar settings in Preferences - sometimes it’s just hidden there. That should get the unlock menu back up Quote Link to comment https://www.insanelymac.com/forum/topic/361206-how-to-unlock-seagate-hard-drive-on-mac/#findComment-2833970 Share on other sites More sharing options...
UrbanExplorer7 Posted June 17, 2025 Share Posted June 17, 2025 Bro, hate to break it to ya, but if you’re locked out and legit don’t have the encryption key, you’re kinda screwed. Best advice? 😂 Kiss those files goodbye and format the disk. I mean, I’ve never seen anyone crack an encrypted drive without the key…unless you’re buddies with the CIA and their crazy quantum computers or somethin’ 1 Quote Link to comment https://www.insanelymac.com/forum/topic/361206-how-to-unlock-seagate-hard-drive-on-mac/#findComment-2833975 Share on other sites More sharing options...
millort_y Posted June 17, 2025 Author Share Posted June 17, 2025 Oh, I should’ve clarified earlier - luckily, I do know the password. My friend originally encrypted the disk on his PC using some Seagate utility, as he explained to me The trouble I’m having now is that there’s an unlocking application stored directly on the drive itself - two actually, one for Windows and one for Mac. Naturally, I’m trying to run the Mac version. But whenever I attempt to launch it, macOS gives me an error saying something like “this application is damaged or incomplete” Quote Link to comment https://www.insanelymac.com/forum/topic/361206-how-to-unlock-seagate-hard-drive-on-mac/#findComment-2833982 Share on other sites More sharing options...

millort_y Posted June 17, 2025 Author Share Posted June 17, 2025 I’m running macOS Monterey on a MacBook Pro 2020 - just recently bought it, actually, as my first step into the Apple ecosystem. Still figuring things out a bit, honestly Quote Link to comment https://www.insanelymac.com/forum/topic/361206-how-to-unlock-seagate-hard-drive-on-mac/#findComment-2834008 Share on other sites More sharing options...
PixelDreamer5 Posted June 17, 2025 Share Posted June 17, 2025 You’ve got two options here - one’s easy and the other’s a bit trickier. The easy fix is to update your Mac to a newer macOS version - your Mac should even handle the latest macOS Sequoia. The issue you’re having is common on Monterey, specifically with those Seagate unlocking apps. In theory, once you update macOS, the problem should go away and the app should launch normally. The other solution is unlockin the drive through the ToolKit app. If you prefer this one, let me know - I can walk you through the process step by step. P.s. also worth mentionin - on newer macOS versions, unlocking with Toolkit works just fine too. 1 Quote Link to comment https://www.insanelymac.com/forum/topic/361206-how-to-unlock-seagate-hard-drive-on-mac/#findComment-2834011 Share on other sites More sharing options...
millort_y Posted June 18, 2025 Author Share Posted June 18, 2025 Hey @PixelDreamer5, could you please elaborate a bit more on the second option you mentioned? I’ve got a couple of apps that only work properly on my current macOS version, so I’d rather not update my Mac just yet Quote Link to comment https://www.insanelymac.com/forum/topic/361206-how-to-unlock-seagate-hard-drive-on-mac/#findComment-2834065 Share on other sites More sharing options...
PixelDreamer5 Posted June 18, 2025 Share Posted June 18, 2025 No problem buddy! Here’s exactly what you need to do - go to Seagate’s official site (https://www.seagate.com/gb/en/support/downloads/) and grab the Toolkit app from there. Install it on your Mac, and once it’s installed, you’ll likely need to authorize it under Security & Privacy settings. Since you’re runnin an M1 Mac, there’s one extra step - boot into Recovery Mode and adjust the security policy if you haven’t already done this. In Recovery Mode (restart holdin down the power button), click on the Security Policy option in the menu bar, and choose the second option - the one allowin kernel extensions from identified developers. After that’s set up, just launch the Toolkit app (it runs in the menu bar), agree to the updated app policy, and you should see your drive pop up in there. Click over to the “Seagate Secure” tab, hit “Unlock”, enter your password, and boom - the drive unlocks, and your files should all show up again Quote Link to comment https://www.insanelymac.com/forum/topic/361206-how-to-unlock-seagate-hard-drive-on-mac/#findComment-2834068 Share on other sites More sharing options...

millort_y Posted June 18, 2025 Author Share Posted June 18, 2025 Phew, it worked perfectly - huge thanks again for all your help! I honestly started thinking I’d never get my files back because of that broken unlocking app on the drive. Really glad it all turned out okay Quote Link to comment https://www.insanelymac.com/forum/topic/361206-how-to-unlock-seagate-hard-drive-on-mac/#findComment-2834087 Share on other sites More sharing options...

oleksandr-lukashyn Posted June 18, 2025 Share Posted June 18, 2025 👤 For future users who might land on this thread, here’s a short guide on how to unlock your Seagate hard drive: If the drive is encrypted with APFS (APFS Encrypted): When you connect the drive or try to access it via Finder, you should see a popup asking for a password. Simply enter the password and click the Unlock button. If the drive is encrypted using Seagate’s own utility: You’ll need to unlock it with the “Unlock Drive for Mac” app, which should be located on the drive itself. ❗️ Important: This app may not function on macOS 12 Monterey. If you’re on Monterey, your only option might be the Seagate Toolkit application. Within Toolkit, use the Seagate Secure feature to unlock the drive. A critical point to mention: If you don’t have the password, there is no way to unlock the drive. The data is encrypted, and without the correct key, recovery is not possible. This isn’t a software lock - it’s full encryption. 1 Quote Link to comment https://www.insanelymac.com/forum/topic/361206-how-to-unlock-seagate-hard-drive-on-mac/#findComment-2834114 Share on other sites More sharing options...
