I am running macOS Mojave 10.14.6 and I want to run an application which was made only for Catalina. I have downloaded “Noto” from the Mac App Store on another Mac (Running Catalina) and copied it on my flash drive. I did it using MY AppleID. When I run it on Mojave it doesn’t start. It says that I have an incompatible macOS version. 1. I tried to edit .plst file in the package contents 2. I tried to run it through terminal The app is not so popular so I can’t just download a .dmg .

I would like to run an app which nominally supports only MacOS 14.0 and above. I am on 12.7.3, and apple won't allow me to update because my computer is too old. However, I know that the app actually can run on my machine because when I run the executable in the app package (game.app > Contents > MacOS > game), it works just fine. Unfortunately, I need to be able to run the app itself because I need to run it through Steam to get networking functionality. Running the app through the command line with open game.app gives me the following error:

The application cannot be opened for an unexpected reason, error=Error
Domain=NSOSStatusErrorDomain Code=-10825 "kLSIncompatibleSystemVersionErr: The 
app cannot run on the current OS version" UserInfo={_LSLine=3863, 
_LSFunction=_LSOpenStuffCallLocal}

I have tried editing the info.plist but there is no tag that seems to specify a minimum system version. Is there anything in the app contents that I might be able to change to override this error? Or some kind of flag I can use to override it when running it from the terminal? (Bonus: does anyone know how to make Steam open the app through the executable? This would also solve my problem.)

I face this situation so often today. I have a MacBook without an M1 chip, and many simple apps on the AppStore for some reason require it. As I see this, they don't have any specific use to it, the app is just built in a way that requires an M1 for some reason. Specifically, I came across the SkyVPN MacOS client and was unable to install it. It is obvious that some VPN apps don't need the M1 chip, for example, protonvpn, IVPN, Tunnelbear and others. Can someone more experienced tell me what is that reason developers require an M1 chip without a reason?

I would like to make my MacOS as minimal as possible without it being unable to boot. The main reason is to reduce complexity and focus on understanding a smaller number of things before adding in more functionalities. In case someone were to say, "That isn't a good way to learn," I would say, that's your opinion, but I would like to know out of curiosity's sake which files I can delete, and which I should not. I am pretty sure there are three permissions groups on Mac - staff, wheel, and admin, which is what you see when you do ls -l - drwxrwxrwx has three repetitions of "rwx", one for each group. I think "sudo" causes you to enter into the second-highest permissions level, but as I tried to delete some system files with sudo, I still got the message "operation not permitted" sometimes. Is there any command to delete those even more restricted files, or is it not a function in MacOS? What is a general explanation for which files/directories can be deleted, and which can't? I think there are some .plist files you can delete, but what I found so far is that when you reboot, the OS realizes something is wrong and goes into recovery mode, where I am pretty sure it regenerates a lot of the files it needs (I think I had this happen for a Bluetooth settings .plist file, for example). But I am sure there are some files that comes with MacOS by default that are not needed, for example, I think I was able to get rid of the Movies and Music directories, and some system files I can't remember, I think it might have had to do with Xcode though. So what can I delete without impeding or harming the system? I tried sudo rm -r * in the top level directory, because I was wondering if since sudo didn't have the absolute top-level permissions, it would not delete any truly system-critical files. So far that has appeared to be the case, as my Mac is functioning fine, but I have not rebooted yet to see what happens then. When I do sudo rm -r * in / or any directory, I get a message asking if I want to override that some file cannot be deleted. I do not see any message about what the expected responses are - "yes", "y"? Does pressing enter mean yes or no? If I hold the enter key down, there can be a huge number of such messages. Is there any way to force the override for the entire command so you do not have to manually answer "yes" to seemingly hundreds of such questions? I think some system administrators will say, "You don't want to do that, that's a bad idea," but the point is I want to know what I can do that avoids the potentially destructive outcome such people may be forewarning one about. Thank you.

I decided that I want to sign up for iTunes Match. But I'm not sure how I can, or even if I can. I visited the "[Subscribe to iTunes Match](https://support.apple.com/en-us/HT204146) " page on the Apple Support site and it says, "To subscribe to iTunes Match, update your Mac to the latest version of macOS." Well, in our household there are 5 Macs. The newest one is from 2016. So none of these machines will run the latest version of macOS, which right now is macOS Ventura. So my questions are: - Is it actually true that one cannot sign up for iTunes Match on any Mac running anything earlier than macOS 13? That seems pretty extreme to me. - Suppose I borrow (or even buy) a new Mac that *will* run macOS 13, and then use that to sign up for iTunes Match by following the instructions on the support page. Will I then be able to use iTunes Match or any of its features on any of my other, older Macs? (The Apple support page isn't clear on what version of macOS is required to actually *use* iTunes Match.) Certainly, some of my older machines run older versions of iTunes and those seem to be aware that iTunes Match is a thing. But if I signed up on a newer machine, would those older machines with older iTunes versions actually work fine (or at all) with iTunes Match? In short, I am *suspicious* of Apple's stated requirements to *sign up* for iTunes Match, and I am *unable to find* any stated requirements for *using* iTunes Match. If anyone can provide some definitive answers on this, that would be awesome. Many thanks!

I was looking at a few games on steam and came across one that read "ATI Radeon HD 2400 or better / NVidia 8600M or better", my macbook has an Intel Iris 1536 mb (8Gb DDR3) and I was wondering if it's good enough to run the game

I am trying to update Xcode to 8.0. My OS is 10.11.6 El Capitan. However I am getting: > **We could not complete your update** > There is not enough disk space available to install the product. I have got 14.22 GB free space. How much do I need? UPDATE: I do not know the exact figure, though I did manage to update with 17.21 GB free space later on.

I'm looking at a game which gives 'Intel HD Graphics 4000' as one of its requirements. My Macbook Pro Retina mid-2014 has 'Intel Iris 1536 MB'; will that be OK?

I have a late-2009 iMac which seems to have held up pretty well, especially since upgrading the RAM to 12GB. I only fairly recently updated the OS to **Yosemite** after running Lion for so many years. The OS update my have made my Mac a *little* slower, but if so then not by a great deal. But I could probably do with updating again — to Sierra — as certain programs require a more recent OS than what I have. I am a bit concerned that running **Sierra** will put too much of a strain on my machine... or **are the requirements not a whole lot different to any other versions of OS X over the last 5 years or so?**

I just bought my first 13" MacBook Pro. Before purchasing new games for my Windows notebook, I used to check the compatibility with [Can You Run It](http://www.systemrequirementslab.com/) , but that site doesn't list Mac compatibility or requirements. Is there any other website where I can check game compatibility for Mac computers? Specifically, I'd like to play Call of Duty 4 and Civilization V. Can I play these games on my 13" MacBook Pro? **Edit:** my system's specification Software Mac OS X Lion 10.7.3 (11D50b) Graphics Intel HD Graphics 3000 384 MB Memory 4 GB 1333 MHz DDR3 Processor 2.7 GHz Intel Core i7 13-inch, Early 2011 with these specifications can i play any of these game on my system?

This just blew my mind. Take for example Medieval II: Total war. Requirement for windows: 512 Mb RAM + 11 Gb free space on hard disk + 128 Mb GPU Requirement for mac: 4 Gb RAM + **32** Gb of free space on hard disk + 256 / 512 MB GPU How come the requirements are so much higher? In particular the size of the games, it's more than double the Windows version! What is going on?

I am planning to buy a Mac Mini and would like to know the minimum requirements to run Xcode 7. I didn't find clear information on this topic.

Using Omni Disk Sweeper, I have listed the very heavy files in my computer in order to, if possible, delete them and free up some space. Of course, I am not going to risk tampering with my system folder, but there are some pretty big files about which I would like to know whether or not it is safe to delete them. Let me know if you know what these files are, and whether it's safe or not to delete them: Private -> var -> vm -> sleepimage (6Gb) and swapfile0 (1Gb) Private -> var -> folders (1Gb) Private -> var -> db (1.4Gb) Library -> Printers (1.6Gb): (I believe I can re-download the needed drivers if I ever purchase a printer from the System Preferences?) Library -> Application Support -> iDVD (140mb) and iPhoto (591mb), not so large but I am not a user of these apps Users -> Shared -> Adobe - 200Mb (is this even accessible by the main user's system?) Users -> Shared -> Library -> Application Support (is this in use?) Users -> Fabrice -> Music -> iTunes -> iTunes Media -> Mobile Applications - 25Gb - (I believe if an app was backed up from my iPhone there, it's either currently in my phone, or not supported anymore, or I can get it from the store again if I've already paid for it?) Users -> Fabrice -> Library -> Mobile Documents (400 Mb) Users -> Fabrice -> Library -> Caches (600 Mb) Users -> Fabrice -> Library -> iTunes (900 Mb) Users -> Fabrice -> Library -> Developer -> Shared (2 Gb) Library -> Application Support: how can I find easily which applications are not installed on my system anymore? In total, more than 50 Gb is used by very voluminous elements whose purpose I am unsure of. I wouldn't ask such a question if I hadn't been using Mac computers for the past 20 years and been able to explore and modify System files for many years; I believe modifying the System files can lead to problems... However some of these files look like they can be rebuilt by the system whenever needed, or are backups files/folders that one can easily part with without any consequences. Thanks for any help!

I was cleaning my MBP out the other day and found chess.app in my /applications folder. I tried deleting it and Yosemite gave me this error:
Is this safe to delete? I was able to delete the DVD Player application just fine. So why can't I delete chess.app? Does this have some system files hidden inside it? Could I simply delete it by doing sudo rm -rf /Applications/Chess.app? If it is safe to delete then why doesn't it let you do it by finder? I mean how many people who use OS X use chess.app?

I'm trying to get the Mindstorms software on my MacBook, and this is part of the requirements: Mac 10.6, 10.7, and 10.8 with the latest service packs What are the service packs it is talking about? Were they on older versions of OS X, but not on the current version? I'm confused because I thought service packs were a Microsoft thing. **EDIT:** I'm currently running 10.10.1 (Yosemite).

I have a fairly old (I am not sure when it was bought) iMac 5,1 running OS X 10.6.8, but I just saw the free upgrade to Mavericks. It looks tempting, but I'd rather first know if my computer can handle this OS before I try to install it. Processor: 2.16 GHz Intel Core 2 Duo Memory: 4 GB 667 MHz DDR2 SDRAM (I guess that covers the most relevant hardware, if something else is important I'll add it.)

Is it possible to install Mountain Lion on a Mac mini that is older than 2009, despite the system requirements ?

I'm considering purchasing a MacBook Pro, but a major issue for me is whether or not it has the computing power to support graphics-intensive applications. Specifically, the two most graphically intense applications I'd be doing are Final Cut Pro video editing (approx. 60 min vids) and playing Diablo 3. Since D3 is the more graphically challenging player here, I'll use it as the baseline. My current MacBook Pro (either 2009 or 2010) struggles with this game to be playable, so I'm a bit skeptical to trust the minimum system requirements for D3 since my current machine meets them: > - Mac OS X 10.6.8, 10.7.x, or newer > - Intel Core 2 Duo (or better) > - NVIDIA GeForce 8600M GT or ATI Radeon HD 2600 (or better) > - 2 GB RAM > - 12 GB Available Disk Space > - DVD-ROM drive > - Video Settings reaching minimum resolution of 1024x768 Getting the obvious out of the way, I can see by looking at MacBook Pro specs comparison that I need to have at the very minimum a 15" or 17" model, since the 13" does not have a separate high-performance graphics card. Additionally, I know that the 15" and 17" both have plenty of RAM and CPU power. The problem is, I have no idea where the MacBook's AMD Radeon HD 6750M/6770M stand against the technical specs. **Would the MacBook Pro be able to reasonably support these use cases (Final Cut Pro and Diablo 3)?** I define "reasonably" as: no choppy frame rate, responsive interaction, and not having to be set the game at the absolute minimum specs just to play *(also, the computer not becoming as hot as the sun would be a bonus, but not a deal-breaker)*.
