I am looking to 'restore' an old iOS game (Mega Jump)—it was unfortunately never updated with a 64-bit release, so can't be run on any iDevices running iOS 11 or later. This isn't an obstacle for me personally, as I'm just looking to download the app and have access to its internal app files (i.e. game assets... for old time's sake :P). **Without access to an old mobile device running iOS 10 or earlier,** is it possible to download 32-bit apps onto my non-jailbroken iPhone/iPad (iOS 16 and iOS 12.5.6 respectively), **or onto my M1 Mac?** I am doubtful about any iOS devices, but gaining access to files [which are clearly still on the App Store](https://apps.apple.com/app/mega-jump/id370398167) (and which I purchased with my own Apple ID years ago) seems like it *might* be more viable on a Mac today? (Note: this developer has not removed their iOS apps from the Mac App Store, i.e. Mega Jump "needs to [be updated] to work with your version of macOS" and an updated game by the same developer, Mega Run, still works.) Am I out of luck? Is contacting the (more or less defunct) developers and gently nudging/begging for a 64-bit release my only option, besides shelling out for an iPad Mini 2 or iPad 4 which may not last more than a year? [Counterpoint: if all I need is to download and copy files from an outdated app, I may be able to borrow a family or friend's old device, but it would be good to know if other options exist.]

I am still wondering if there's a big archive of all and old IPA files that was on AppStore long years ago. Because most of 32bit games is deleted from AppStore after iOS 10-11 release. I saved some of them from my purchases sections, but not all of them is available for download from there. I don't understand why. Isn't it possible to "catch" Apple server link, where it stores all IPA versions of games for certain iOS versions? It would be great, because current ways to install older version of apps (or deleted apps even) are so difficult. That's sad, because there are ton of various iOS games that lost forever due to Apple strict applications rules etc, due to 64bit games later. I don't have many apps in my purchases list, and of course I can extract them, but I can't decrypt them, I don't understand how to do it, to share it with anyone. Thanks! P.S. Some games included inapp purchases. Because of games being so, so old, now server doesn't work at all, and you can't buy anything, because server not responding, and Apple server too. I don't know also, how to bypass it to unlock content.

I have a Windows app ([LROverhaul](https://github.com/LunaKampling/LROverhaul/)) that was formerly able to run in MacOS. It was a Windows .NET app that used Mono to run it. However, when Apple removed support for 32-bit apps, the old way (mono --arch=32 linerider.exe), it gives me a "Error: --arch=32 Failed to switch to 'mono32'." message. I think this is because MacOS 10.15 dropped support for 32-bit apps. Is there any "virtualization layer" that can run just in the terminal to enable the use of this app? I don't want to have to run a VM to use this. Also, see my question [How do I run a .NET 4.8 app with Wine on M2 Mac](https://stackoverflow.com/questions/77247649/how-do-i-run-a-net-4-8-app-with-wine-on-m2-mac) on Stack Overflow about running the app on Mac.

This question arises from an earlier question in which the top answer suggests 32-bit support in Catalina is "disabled" but possible to re-enable with the help of library files copied over from Mojave. For those who have implemented the workaround, does your experience (OS stability, performance of legacy software such as CS6 and MS Office 11, etc.) suggest this is a viable alternative to running an older 32-bit supporting macOS in virtualization under Catalina?

Apparently since macOS Catalina 10.15 Mac disabled support for 32-bit apps? How can Steam games like Portal 2 be played on MacBooks that have been keeping up with macOS updates? In my case I'd like to do this on Intel MacBooks from 2015.

==> Caveats
wine-stable supports both 32-bit and 64-bit. It is compatible with an existing
32-bit wine prefix, but it will now default to 64-bit when you create a new
wine prefix. The architecture can be selected using the WINEARCH environment
variable which can be set to either win32 or win64.

I can run IrfanView app like here:

wine64 /Users/msciwoj/Applications/Wineskin/iview460_x64/i_view64.exe 
00c4:fixme:imm:ImeSetActiveContext (0x257ae0, 0): stub
00c4:fixme:imm:ImmReleaseContext (0000000000010020, 0000000000257AE0): stub
0024:fixme:imm:ImeSetActiveContext (0x174690, 1): stub
0024:fixme:imm:ImmReleaseContext (0000000000020050, 0000000000174690): stub

but I can't do same with it's 32-bit counterpart:

wine64 /Users/msciwoj/Applications/Wineskin/iview460/i_view32.exe 
00c4:err:wow:load_32bit_module failed to load dll c0000034

The thing is I am trying to run other software Jpegcrop which is another small (single .exe file) win 32-bit application which doesn't have its 64-bit equivalent and it's failing in identical way as 32-bit IrfanView above:

wine64 /Users/msciwoj/Applications/Wineskin/jpegcrop.exe 
00c4:err:wow:load_32bit_module failed to load dll c0000034

While it seems impossible to get the Jpegcrop 64-bit binary version from the developer and I am now forced to use only 64-bit apps (MacOS 10.15 Catalina) - is there any alternative way to run this app with Wine on my Mac?

I recently read this post on netkas.org about running 32 bit command line apps on Catalina using Mojave 32+64bit libraries and frameworks, adding to the nvram boot-args the option no32exec=0. I extracted with Pacifist the /usr/lib, /System/Library/Frameworks and /System/Library/PrivateFrameworks folders from the Mojave installation app to ~/.mojave and then tried to run this 32 bit macOS app with the following terminal command: $ DYLD_ROOT_PATH=~/.mojave /Volumes/Lazesoft\ Mac\ Data\ Recovery/Lazesoft\ Mac\ Data\ Recovery.app/Contents/MacOS/Lazesoft\ Mac\ Data\ Recovery Here is what I get running it: 2020-06-08 17:26:18.630 Lazesoft Mac Data Recovery[1881:56237] /Volumes/Lazesoft Mac Data Recovery/Lazesoft Mac Data Recovery.app 2020-06-08 17:26:18.630 Lazesoft Mac Data Recovery[1881:56237] /Volumes/Lazesoft Mac Data Recovery/Lazesoft Mac Data Recovery.app/Contents/MacOS/ifsui 2020-06-08 17:26:18.632 Lazesoft Mac Data Recovery[1881:56237] Error Creating Initial Authorization: -60008 2020-06-08 17:26:18.632 Lazesoft Mac Data Recovery[1881:56237] AuthorizationExecuteWithPrivileges failed! Trying to run ifsui from the same app bundle I get the app to open in the dock but nothing appears on screen and this is what I get on the terminal: _RegisterApplication(), FAILED TO REGISTER PROCESS WITH CPS/CoreGraphics in WindowServer, err=-304 2020-06-08 17:21:38.555 ifsui[1836:52747] *** WARNING: Method userSpaceScaleFactor in class NSView is deprecated on 10.7 and later. It should not be used in new applications. Use convertRectToBacking: instead. I know I'm probably asking something that cannot really be done, but is there any way to make this workaround work with more than command-line programs?

I am trying to install a linux distribution called Ubuntu MATE onto a 2006 Mac Mini. I can’t get 64 bit install media to boot but I can with 32 bit. The Core 2 Duo in the computer is a 64 bit CPU so it should work, how can I fix this?

I know that 32-bit apps will not work on MacOS Catalina. Unfortunately, I use Hangouts very often and the plugin requires the use of a 32-bit app. As far as you know, is there the possibility to make Hangouts work on Catalina? Thank you so much in advance.

I have a problem with Safari on different macOS versions. Is there any information from which version Safari doesn't support 32 bit architecture? Like Firefox (from v.56) and Chrome (from v.74) on macOS.

I've been putting off upgrading from Mojave 10.14 to Catalina as I know I have at least one paid-for 32-bit app which doesn't offer a free upgrade. This question talks about manually detecting 32-bit apps prior to installation: https://apple.stackexchange.com/questions/289195/how-can-i-find-out-which-mac-apps-are-32-bit But I wondered, when Catalina is installed will it check for such apps and warn me they won't be usable? Further, will it tidy up by removing such apps or will I end up with non-runnable apps to manually clean up?

macOS Catalina is said to have dropped support for 32-bit apps. It’s not clear how much support is dropped. Is there any supported way for a 64-bit app to request the kernel to create a 32-bit code segment?

I get this pop-up warning on one-off installers and such irrelevant situations. I understand it's to encourage a migration away from 32-bit apps; fine, but there's nothing I can do about it. It's getting on my nerves. Is there some way to put a stop to it altogether?

Since the launch of Catalina I've been getting this popup about "Flash Player Auto Update Daemon" that I cannot figure out how to get rid of, even though I'm still using Mojave. I know it's a 32-bit app but I can't find it in the Applications folder. I checked the Legacy Software list, I see the suspect: **fpsaud**. I found its folder /Library/Application Support/Adobe/Flash Player Install Manager. Can I simply delete this or is anything going to break? Is there another way to get rid of this popup?

I've delayed updating to Catalina due to a few applications which I will lose access to, due to them being compiled for 32-bit architecture. While the third-party apps are not overly difficult to address, there is one Apple app which I still use and rely on, Pages '09, and cannot go without.* Are there any ways to find 64-bit ports of 32-bit Apple apps, like Pages '09 ? ___ *Before anyone comments, yes I know that there are newer versions of Pages, but when I'm writing, I much prefer the UI of the older version, so newer versions are a non-option.

On June 28, 2017, Apple announced that > macOS High Sierra will be the last macOS release to support 32-bit apps without compromise. How can I find out which apps on my Mac are 32-bit so that I can see if I need to upgrade them?

I know that 32-bit applications do not run on iOS since iOS 11. Prior to iOS 13, attempting to start a 32-bit application resulted in an > “This app” Needs To Be Updated alert. Now the screen becomes black for some seconds, and then the lock screen (where you have to enter your code or Touch ID) appears. So I thought this might be a good time to remove all remaining 32-bit apps from my device. But how to find them all? Prior to iOS 13, “Settings > General > About > Applications” listed all incompatible apps. That list does not exist anymore. Is there an alternative method to list all 32-bit applications, so that I can delete them?

It's long been telegraphed that 32-bit apps will no longer work in upcoming versions of macOS. This is rather annoying, because my go-to games when I want to waste 15 minutes are all 32-bit from companies that no longer exist. Does anyone have any ideas whether there will be any way to run these apps, perhaps in a wrapper? No, booting another OS is not a solution. Is there any info on this issue at all?

I am running Mojave 10.14.6 (on a late 2013 MacBook Pro), waiting to upgrade to Catalina. Checking for 32bit applications lead to a list containing /System/Library/Frameworks/DiscRecording.framework/Versions/A/Resources/draudiotool /System/Library/Frameworks/AppKitScripting.framework/Versions/A/AppKitScripting /System/Library/PrivateFrameworks/vmutils.framework/Versions/A/vmutils /System/Library/PrivateFrameworks/CoreMediaPrivate.framework/Versions/A/CoreMediaPrivate (which seem to be mostly Unix executable files), some dynamic libraries, a few apps, and then some items like this /sbin/autodiskmount /usr/sbin/pictd /usr/lib/libnetsnmp.5.2.1.dylib /usr/bin/qc2movie Are these 32-bit code files that are going to block the use of apps, even if the apps are 64-bit? Will installing Catalina remove them, or should I delete them first? I can delete the apps (don’t need or can upgrade them), but is there anything I can do ahead of time with this list?

I read somewhere that Adobe Illustrator CS6 is 64-bit and able to run on Catalina. I did run a 64-bit software check on OSX Mojave to double-confirm that it is 64-bit before upgrading to Catalina. I am now left with a defunct Illustrator and Photoshop which I needed to rush my stuff! This is what I see on my dock after Catalina upgrade! >
