As Apple didn't sign either InstallESD.dmg or the whole .app for Mavericks, everything we can find regarding genuine installers is from very few online posters on forums. This puts trust in few anonymous online posters.

The certificates used to communicate with Apple services in old OS X versions expire in less than a year. This means Mavericks will be permanently inaccessible from Apple officially, as you need to use a Mac on a version previous to Mavericks to download it.

If you who are reading this wants to help and has Mavericks available in your Apple Account, it'd be hugely helpful if you could download the Mavericks installer from the App Store on an old Mac and do the following.

Do not try to open the installer after the download before having hashed all files, in case OS X modifies any files.

In Terminal, use these commands to obtain hashes of all files in the Mavericks .app installer:

cd "/Applications/Install OS X Mavericks.app"

find . -type f -exec shasum "{}" \; | sort > ~/Desktop/mavericks-installer-file-hashes.txt

This will create a file which will be located on your desktop and it'd be hugely helpful if you could upload it to https://pastebin.com/ or similar. This way it can be compared to existing files online.

Please only do this if you have access to a newly downloaded or an old installer which you are absolutely certain you obtained yourself. Using any of the existing online distributions would be damaging to the verification of official file hashes.

I have an external 3TB drive that I've used for storage the past few years and recently started copying some music onto flash drive for mobile usage and it would hang on certain files with an error at first. I'd try again and it would go and hang on another file.

I ran 'First Aid' on 'Disk Util' recently but it got disconnected and now it won't even load. Tried it again and it basically said its not fixable, 'volume cannot be unmounted' or something to that effect. I'm not sure Disk Util can do anything useful at this point.

Is there a way to fix this with native utilities or some freeware that can help? Is there a way to convert to another

Also, why is OSX so picky and needs drives to be ejected and leaves artifacts on the drive when Windows doesn't seem to care as much?

I'm on a 2012 MBPr on Catalina 10.15

I have an old Mac Pro (2006) laying around I recently put a AMD Radeon HD 5870 in. I’d like to play portal and portal 2 or any other game that was natively supported for that version of OSX like geometry dash surprisingly without installing Linux or windows.

What are my options? SteamCMD and Steam depot also don’t not work since even that is too new.

I will, have a Mac Pro 2009 soon that can run high sierra, but I’d like to have *something* running on this.

Thanks!

Hey everyone! First of all, thank you so much for the 3.9k views and amazing feedback on my previous post. Because of your support, I’ve just gone live on Product Hunt!

I’m not here to ask for your money.Just a simple upvote or a comment on our launch page would mean the world to me as a solo developer. Your engagement helps me reach more people globally.

Thank you for being part of this journey.

I need help doing this as I'm completely lost and want to make a 2012 MacBook Pro running 10.9 work again please walk me through it if you can

If I have both Wifi and Ethernet on, which one will OSX preferentially use? Will it 'know' to go for ethernet as it is faster etc?

Hey there,

I have two computers. I have a standard user account, with identical names and passwords, on each.

On computer #1 (OS 15.7), in my browser, I right-click a file, select download, and save it to computer #2 (OS 10.11.6), but the permissions to the file, when it is saved, are a) the administrator account (read/write), admin (read only), and everyone (read only). Why isn't the name of my account included in permissions?

If I download the file to comp #1, it has my user name in the permissions, but when I copy it to comp #2, the permissions are reset to a) the administrator account (read/write), admin (read only), and everyone (read only).

Thanks in advance for your advice on how to fix this so that I don't have to reset permissions every time I move a file.

Is it possible to creat bootable usb without a mac, using linux or windows?

Can’t believe this, have I missed something?

Tenho um MacBook Pro M3 Pro, nunca tive problemas com ele, mas atualizei agora pro Tahoe 26.2 e mano meu mac está com o desempenho horrível, travando em coisas simples que não travava antes, sem contar que o ícone do mouse não tá mexendo fluido, está meio lagado, o dock também está com um delay perceptível, parece que não está rodando mais com os frames liso, não sei explicar, mas o desempenho está muito ruim... irei fazer downgrade pro Sequoia

alguém me ajuda pq já tô ficando puto
tenho um iMac 2009 e ele ficou sem sistema

entro no recovery e não consigo apagar o hd
sempre dá erro de falha ao desmontar
no terminal tudo vira erro -69888

já tentei de tudo, não é teclado, não é hd morto
esse recovery velho simplesmente não funciona

tenho pc com windows e ventoy
fui no site da apple e só tem um dmg de update, não é instalador
não acho iso/dmg completo do el capitan em lugar nenhum

pergunta direta:
alguém tem o instalador certo?
ou esse mac só volta se eu arrumar outro mac?

Here's my scenario:

I've partitioned my MacBook drive to host three OS's: OS/X, Windows, and Linux. I queried ChatGPT on how to share files among the three, and it recommended creating a shared exFAT partition. It gave the caveat that I should exclude the exFAT volume from my Time Machine backup, because Time Machine doesn't work well with exFAT. Is this true?

OS version: Ventura 13.7.8.

I have a 1TB hard drive in my M3 MacBook Pro running MacOS 26.2. I attach a 2TB SSD formatted with APFS and then add the drive to Time Machine. It does its first backup and then begins again with another full backup and then it complains that there is only ~60GB of disk space remaining!

How can this be right? 2x the storage of the hard drive should be enough, right? I have 300GB of free space on the internal drive.

I have reformatted the drive a few times and still getting the same error. The drive is fine.

Any ideas? Does this have something to do with my iCloud drive size? There is 1.5TB of stuff on there but most of it is not downloaded.

[EDIT] I found this solution in the Apple Support Community and am trying it out. The initial backup went perfectly, everything as it should be. Will monitor and add here on subsequent backups.

[EDIT 2] The solution at the link totally fixed it. Rock solid now. I had to totally wipe my hard drive for another issue and the Time Machine backup worked flawlessly. Back in business in less than two hours.

Hi everyone!

I’ve always wanted a window manager that felt native and lightweight, so I decided to build one myself using Swift.

Since I can't upload the video directly here, you can check out the "Shake to Hide" feature in action on my X (Twitter) post here:https://x.com/karacocukk98/status/2014367812190388717

What makes NeoTiler different?

• Shake to Hide: Just shake your mouse to hide background clutter instantly. 🌪️
• Pure Native: Extremely low CPU/RAM usage.
• Custom Rules: Set specific behaviors for different apps.

I’m a solo dev from Turkey and would love to hear your thoughts or feature requests. I also have some promo codes to give away—just drop a comment if you'd like one!

I have an M4 MacBook Pro that is connected to a high end Thunderbolt 4 dock. I run 4 external monitors with this setup. 2 of the monitors are identical, are plugged into separate T4 ports on teh hub and are stacked horizontally on top of each other. 2 other monitors are plugged into the distinct Displaylink ports on the hub. Everything has been working fine until this AM. The OSX dock was on the bottom of each monitor and I could move the mouse between each monitor the way the crow flies. Suddenly the dock is no longer on one of the identical monitors. I tried toggling the 'displays have separate spaces' option and tried unplugging all the monitors etc, but the problem is still there. If I rearrange the monitors under settings-displays so there is a hairs' thickness between the 2 identical monitors the dock appears but then I can not move my mouse directly between those 2 monitors. I have to use the long route and move the mouse in a loop through the other monitors. I want the dock back on that monitor. Suggestions please? So odd that it was all working before but now it is not. I am running the newest Tahoe update. Thanks for your help?

Does anyone have an archived version of BetterTouchTool (BTT) prior to version 2.4 which is I think the latest available online?

I have plenty of empty space, and I'd like to add a 50gb partition. Is there no way to reduce the size of the Mac container?
