Near the end of the Mavericks installation, I ran into the "This copy of the Install OS X Mavericks application can't be verified. It may have been corrupted or tampered with during downloading." error.
Check that the date is correct. This is an error that can be received if your date is set utterly incorrectly, typically due to a flat battery prior to install and not being able to connect to an NTP server to correct.
I am looking to upgrade the Lion partition to Mavericks, because Mavericks has some features I like, such as a working Safari. I was looking around and I cannot find the "Install OS X Mavericks" application on the App Store. Apple's support website only has a link for El Capitan, which leads to the actual question. Where, short of downloading a .dmg from a website, can I find the Mavericks install application?
I followed @Rich's suggestion and I was able to download the package and install it which I wasn't able to do before, but I've found that I still don't have access to a lot of the commands that I should like arp or diskutil just to name two that I've encountered recently.
This should then take you to a link which will require a developer Apple ID sign in. From there, you'll be redirected after authenticating to where you can manually download and install the Command Line Tools.
If your terminal still says you need to install command line tools, it may be an issue with gcc-4.2. I was able to confirm that was the issue by following my terminal message after I ran "bundle install" on my rails app. If this is your issue, you will do the following follow Housen's solution here. Best of luck
I spent the day trying to solve this problem. I believe the error messages are just confused about installing Xcode. The real problem I had was a need to update gcc compiler. This happened to me because I skipped Mountain Lion, where that occurred. This blog post was very helpful.
/Library/Developer/CommandLineToolsMy case is: I tried to install brew on my new mac. After I installed Xcode, there was nothing in the above path but the command line tools were somehow installed to another location. (xcode-select -p tell me it was /Applications/Xcode.app/Contents/Developer)The way in stackoverflow can install the command line tools to
To do so, Apple says customers can copy the OS X installer to the /Applications folder on each Mac and then run the installer from there, or they can create a NetInstall or NetRestore image, or use Apple Remote Desktop.
First and second generation of Mac Pro's (Macpro1,1 and Macpro2,1) have 32bit EFI and because of that since Mac OS 10.7 Lion there was no easy way of installing higher versions of Mac OS on them. Then ML Post Factor came and enabled installation of Mac OS 10.8 on unsupported, legacy Intel Mac's. The same guys are currently making MacPostFactor for Mavericks, but until it's out, here's copy/paste of a guide from Macrumors, together with links bellow! It works great, i'm typing from my Mac Pro 1,1 (firmware hacked to 2,1 gen) running Mac OS 10.9 Mavericks!
Guide is bellow, my advice is that you MUST use guide bellow for creating Mavericks installation USB. Do not use automated Lion Disk Makers, it will not work (Lion disk maker is great, but it won't be good in this particular scenario!). Good luck!
EDIT: This is a clean way of installing Mavericks on "legacy" hardware. There's been a way to install Mac OS Mavericks via Chameleon bootloader which would make your Mac Pro a hackintosh, but it required much more work.
gcc takes a long time to build, over 45 mins, unless you install command line tools and grab a precompiled, bottled version. Terminating brew with Ctrl-C is safe, and brew will not symlink to /usr/local/* until it has finished installing, so you don't have to worry about the extra stuff. Finally, the point of getting gcc was getting gfortran for scipy, but avoiding common problems in pip install and getting scipy can also be done with the homebrew-python tap.
Everything went smoothly - except that my Python installation completely broke. This was a big break - I work in Python almost everyday. By broke, I mean that Apple wiped out all of the python libraries I've installed - pip, virtualenv, numpy, matplotlib, ipython, pandas, flask, greenlet - all gone.
All of which end of failing either before or after the initial installation (before it reboots and continues) with an error that the operating system could not be installed, but it usually does not point to any specific error, just says something like try again.
I tried just about EVERYTHING. I installed mavericks, tried updating EFI (it said not applicable), tried yosemite, el capitan, etc. Tried installing via recovery mode download, tried app store downloading. I EVEN CALLED APPLE
In the end, I used a macbook pro to install High Sierra onto an ssd and then transfer it to the mac mini. It worked and booted, BUT, after an OS update was applied, I ended up with the same error message about the installation failing.
My only guess at this point is that it is a firmware/EFI problem. I am confident that any drive that already has the OS installed would boot on this machine, but as soon as any OS type update is needed (either to a newer OS, ie 10.10 to 10.11, or even a combined update ie 10.10.1 to 10.10.5 or something)
@ajcooke01 I will be very reticent to install this for some time. Apple did so many nasty things to hurt third party repairers with High Sierra, they may never regain my trust. They cost me months of un-needed work and worry.
I would like to install Metasploit with MacPorts because until now, all the best security tools I needed were correctly manageable with MacPorts through 4 different versions of MacOS X (Snow Leopard, Lion, Mountain Lion, Mavericks).
(This installation challenge is part of a baptism by fire.)
@spacetime: Since "installing" a macOS app involves simply dragging the app to a folder, it's certainly technically possible. But what's impossible is using 1Password 6 on Mavericks. The OS will refuse to run it.
As is often the case after a Mac OS X upgrade, installing Ruby gems that depend on compiled C code can require a bit of fiddling about. I've just upgraded my laptop to Mavericks, and lo and behold, the nokogiri Ruby gem won't install. I should have had déjà vu here, as I went through a similar process installing nokogiri on Leopard!
The standard advice online for getting the XCode command line tools installed on Mavericks is to run xcode-select --install. So I did that, and a small dialog popped up and then proceeded to download the command line tools for me. I rather thought I was set at this point. But no...
If, after re-running gem install ... you find that the gem still won't install, and that the configure.log file still complains that you don't have any command line tools, try cd-ing into the directory of the code that won't build and running make.
Note that I didn't run XCode 5 inbetween upgrading to it (in the App Store app) and trying to build any Ruby gems. When I did finally run it (after I'd successfully got gcc installed), I was presented with a dialog box asking if I'd like to "install additional required components?"
UPDATE: Since writing this post I've upgraded to Mavericks on a second computer, ran into the same problem, and launched XCode. After it had installed its missing components I could run gcc without being prompted to accept a license agreement, and gem compilation just worked. Also take a look at the comments below, where others have been explaining what's worked for them.
The process of a clean install is not difficult if you follow these instructions, but because it involves formatting the Macs hard drive, it can result in extra work. Since the Mac will start with a clean slate, all apps must be downloaded and installed again, important documents and personal data must be manually transferred back over from backups, and system settings must be customized again. This typically makes it more appropriate for advanced users or for select situations (like selling a Mac), and thus it should not be considered a standard upgrade path to get to OS X 10.9 Mavericks.
Warning: Performing a format and clean install of OS X will erase the Macs hard drive and all contents on the drive will be removed. All files, applications, documents, photos, customizations, everything on the computer will be lost in this process. Understand this and know what you are doing, and why, to prevent data loss of critical files. We can not reiterate this enough.
Fresh install of Mavericks happening as I type this comment! People if you follow all directions carefully including spell check when creating boot disk all will work!! Thanks for for all the great info!
I need to install XCode on Mavericks. What is the last version of XCode that is supported on Maverics and how do I get it? Current version of XCode requires Yosemite and unfortunately don't whant upgrade to it with my iMac for now ?
Which version, additional files do I have to download.
By the way, I'm not a pro.
I uninstalled Mavericks from a Macbook and went back to 10.8 Mountain Lion which shipped with my computer. I was having lots of trouble with Bluetooth and wireless. Also had problems with a black screen after sleep. Bit of a bummer if you cannot close the lid on your laptop. Google search will show you these are pretty common problems. Some of them go back before Mavericks but they all started for me when I upgraded to Mavericks.
I wonder if I could partition my HD, and install Mavericks in the new partition. Then install Rhino in that partition too. If Mavericks does not work properly I could remove the partition and be back to normal? I would need to talk to a Mac expert to find out if that could work, and how to do that.
Instead, I would install Mavericks on a FireWire external drive. Then you can boot to it when you want it and can easily go back and forth. You can even use that external drove on another Mac to test out different hardware combinations.
