I have a trouble, the last version of OSX (10.13.4) is incompatible with my system, but I absolutely need OSX 10.13 to install the last version of xcode who support iOS 11.3. I look in the developer download section of apple (I have an Developer account) but I can find only 10.13.4.
It's sound completely crazy that we can not find by legal way a previous version of OSX (like 10.13.3), so maybe I miss something and I open this stackoverflow question.
How developer can test their software on previous release of OSx if it's impossible to find them ?

I actually built a Hackintosh to learn programming with Xcode. It runs on my Asus X555LA laptop. I downloaded the latest Xcode 9 GM build from the Apple Site (not from App store). After extracting, when I tried to install, it shows "You can't use this version of the application "Xcode" with this version of macOS; You have macOS 10.12. The application requires macOS 10.12.6 or later".
Is there any tweak to make it run on my Sierra 10.12 itself? I can't really think about upgrading the macOS version as it's a Hackintosh. I followed this guide to install macOS on my Asus laptop.
Xcode requires latest macOS, you have no choice, you need to upgrade the macOS version on your Hackintosh. Or better: Reinstall macOS in a recommended way on your PC, if you're doing Hackintosh... :)
The guide you linked is very poor... Never use premade install images, because these have been modified in an uncertain way, and you don't want to install a premade undocumented mess to your computer. It might be packed with threats, malwares, spy tools and so on.. It's the worst thing I can imagine in security aspect to install an OS image from uncertain source.
Also, there is no universal macOS installer for PCs - even though many are trying to find a way to create it: it's a bad idea and it will never succeed because there are so many PC parts, millions of differently built computers..
The only way to create a stable fully functional Hackintosh is to know your hardware and create an installer flash drive for that specific PC. First you have to download the latest macOS Sierra from AppStore, this is the only source that you can trust, because it's downloading from Apple's servers. Then install a small program, called Clover bootloader to the flash drive to make it bootable.
This is the only full and up to date guide for PC laptops. If you have questions, register to the linked site and start a new forum thread posting your questions. They will help you but please read this guide at least 3-4 times carefully because everything is described here.
I can't install Xcode 4. I have some files that I need to open in Xcode 4. However, when I try to install it, it says "Xcode Install Assistant cannot be installed on this disk. The version of OS X is too new." How can I make it think I'm on Lion or Mountain Lion?
Here is a picture:
Download it in the App Store - it's the newest version and looks like the disc you have doesn't support Mavericks.
I feel tired of these preposterous answers. I think that if you want to stick to an older version of something, you should be able to. Also, I don't think software like XCode 4 are that old anyway.
But, to the point: I think XCode 4.6.3 is compatible with Mavericks. I am not sure about previous 4.6.X, but I think none of them work.
Any versions prior would require a previous operating system. I think you could try using pacifist to install the version you want, but I haven't found any guides.
If your problem is with project compatibility, in XCode 5 there is an option to save the project in a way it is compatible with XCode 4.6, and I suppose 4.6 offers a similar option to save in a version prior. Of course, you may need to adapt the code of the projects accordingly. Usually I try to stick with the Snow-Leopard-compatible code, because it compiles fine in all XCode 4.X and 5.X versions.
You can download any of these from the developer website.
I would try partitioning the disk and installing an older Mac OS X. I work with Snow Leopard and Mavericks in the same Mac. I usually do interface tasks in SL and the rest on Mavericks. The other advantage is that I have both XCode 4.2 and 3.2.6 in the same machine, so I can manage some backwards compatibility. =D
I recently upgraded from Lion to Mountain Lion and my Xcode4.2 stopped working. It complains about it's not for Mountain Lion. I also installed Xcode4.4. But I have an important project that works under Xcode4.2 but had issues with Xcode4.4.
Is there a way to make Xcode4.2 work under Mountain Lion???
I didn't find a version for Mountain Lion on Apple Developer website...
The reason you can't find Xcode 4.2 for Mountain Lion is that there is no such version. In the past, people have used tricks to get older versions of Xcode to run on newer OSs—but, much like the tricks people have used to run older SDKs in newer versions of Xcode, etc., Apple has intentionally or accidentally broken every one of them.
It really isn't worth fighting them on this. If you can get your code working in 4.4, do so. If you can't, keep a Lion machine (or virtual machine) around to build it with.
Xcode 4.2 isn't supported on Mountain Lion. In fact, it's pretty old at this point, and it's not getting any younger. You're going to have to update your project to work with newer versions of Xcode at some point anyway -- why not take the time to do it now? Xcode 4.4 will let you deploy to systems going all the way back to 10.4.
I'm planning to buy Mac OS Lion, but I would like to know some informations.
- Are Snow Leopard's apps compatible with Lion?
- Are apps compiled with Xcode for Lion compatible with Snow Leopard? What if these app uses popovers/fullscreen which are features of Lion?
xCode requires a full download (the full 5*ish GB) and if you are a Java guy you will have to re download Java as it is not included (this was my experience when opening eclipse for the first time in Lion).
Some of Snow leopards apps are compatible, not all (ppc apps will not work). It is probably best to check with the software vendor first.
Another thing your Library folder disappears on an upgrade among some others where Lion is trying to 'Protect' its users. To get round this simply enter the command into terminal. (replace username with your username and foldertoreveal with the hidden foldername)
chflags nohidden /Users/Username/FolderToReveal
The upgrade process other wise has been fine. For reference I am an Obj C /C++ /C and Java developer. Hope this helps
Also will link you to this post about Developing Java on Lion:
Stack Overflow post on Java in Lion
A very good list of compatible applications is available at RoaringApps. I highly recommend checking for your favorite editors/IDEs/etc there.
Of note:
TextMate: "Works fine," but there are some issues
BBEdit: "Works fine"
iTerm2: "Works fine" (minor interface bugs)
And of course, Apple's tools require an upgrade to XCode 4.1.
As far as developing with the new APIs in Lion, you can explicitly target a specific version of OS X for compatibility. When building for 10.6, those new APIs will not be exposed during compilation and you will get warnings about unrecognized selectors if you try to use them.
So far what I've noticed :
- make sure you install XCode 4.1 (not the same as 4.0, it's a free separate download), which fixes the Python includes mess
- go to terminal and type "java", this will trigger the download of the Java runtime
But I chose to avoid the burden of fixing all libs by going with a clean install of Lion (from a USB key)
cvs stopped working for me, but downloading Xcode seemed like an unnecessarily heavyweight fix. Adding /Developer/usr/bin to my PATH fixed it for me.
itunes asked me to upgrade my iphone's OS to 3.1.3, so I complied naively.
then xcode told me that the latest iphone OS version it could support was 3.1.2. So I went to download a new version from https://developer.apple.com/iphone/index.action#downloads, xcode 3.2.2 with iphone SDK.
but when i went to install that, i was told I needed snow leopard 10.6.2 or later. so I'm just making sure that I am not misinterpreting anything when I say that, given that it is impossible to downgrade iphone OS versions without jailbreaking, I need to install a new version of the OS just so I can resume testing apps on my iphone?
given that it is impossible to
downgrade iphone OS versions without
jailbreaking
I'm not sure that's correct. I've done it before on ipods. If you go to ~/Library/iTunes, there's a few folders in there. Look through the folders for files with an "ipsw" file extension. These are the software upgrades. When you perform an upgrade, the upgrade file is saved here. So find the one you want to "downgrade" to. If you can't find it you may be able to google for it. In any case find the appropriate file. Then in iTunes if you option-click "Check for Update" it asks you to choose the file you want to use to perform the update instead of running the update check normally... so just select the ipsw file. That should "downgrade" you... I think. As I mentioned I did it a few years ago on an ipod.
