  • I spoke with Apple again and they said to wait a while and try installing it again. It's now been two days and I've rebooted my Mac a number of times, and have attempted installation many times. I also tried installing all other software updates in case that was a factor. They all updated fine without any problem. The only thing I can't do is get the Mojave installer to run because it is apparently "damaged".

    Maybe this is the universe telling me not to upgrade and I should give up, but now I'm here to ask you good folk. Just try to download it again. That's all. After searching for how to fix this after I had erased my drive leaving me with no system, I have figured out how to fix it without having to download the installer again.

    The suggested fix worked perfectly. It is sad how less Apple is taking care for its own community. Even if we use older equipment we still support Apple and we purchase equipment. Not so much as they wish but we do. Hey make sure you click the link in a safari window, at first I was clicking from firefox and took me to the App store home page. Then I tried it on Safari and it took me to Mojave download. I did this last night by changing the clock. I did the clock thing bc I had the same problem and was able to finally install Mojave.

    Think I did this before, once I read it I remembered this trick. Redownloading does NOT work. I wanted to upgrade to Siera and it was just finished and still got that error. Hope the rest of this article does have true facts. Redownloading does work but sometimes you must reboot the computer to clear the certificate date. Do I need to change my clock before I click the link to try and download? You need to find the Install Mojave app in the Finder and delete it before downloading again.

    It secretly downloaded an installer when you first pressed Open. AND you have already redownloaded Mojave, then reboot the Mac. It will clear out the certificate. Wow that work! I had a old installer for mac sierra that I needed for a old mac and that was the issue! Thanks, save the day and the client brick mac! Thank you thank you thank you! I thought I was screwed this allowed me to get High sierra! Confirmed, it worked immediately without the need to download.

    How did you work that out? What puzzles me is why Apple allows this problem to persist. Holy stuff —thanks so much Howard! You saved the day after many frustrating hours and endless re-downloading, restarting, and booting in safe mode. Your instructions are clear and they worked like a charm! The Mojave install app had been store my documents directory for over a year.

    Once again I got the error when I tried to run the install app, but after deleting the Installinfo. This was very helpful! After many failed attempts to download Mojave using suggestions from other sources, including Apple your suggestion was the only one that worked. Thanks Howard — this is brilliant! Spent an hour wrestling with this problem, and then app your post. Worked liked a charm.

    You are a life-saver. Then you can run even the old expired installers for MacOS Mojave and older too if you set the clock back even further. Key is to match store date to where the installer download was from. Never ever upgrade your OS until all your software vendors confirm they support it. You learned an important less, sucks that it had to app the hard way. So a certificate has expired and so I need to renew it and here are my questions: 1.

    Can't Install macOS Mojave - Apple Community

    The other option, which is silly, is to set the clock back a year or so. Also just my opinion but I think Mojave is better than High Sierra. Catalina is not good I would avoid that one. Thanks to jimmmm it worked tried to use two mojave before my calendar. I have changed the date from the terminal, but before this i have switched off my wifi so it this not connect in order to change it back.

    It did work afterwards starting up from the USB Mojave. This was the comment that helped me. I was trying to install Mojave into a VM. I followed the directions to change the date to Aug, 18, I bought a used MacBook Pro for almost no money at all, the reason for the low prize ,97 USDwas due to an update causing the MacBook pro to show the black screen at startup flashing folder with question mark.

    I used my laptop with windows and downloaded the MacOs i needed to create a USB drive for a reboot, but i had the same problem when i tried to install the damn thing. After changing the date and loading the new OS, can I change the date back so all my apps work calendar, reminders, iCloud…? I did the same thing, and it worked! Admittedly, I found an old version of MacOS Sierra on a torrent site the official link for the old version did not work but otherwise the process is the same.

    This will be reformatted, so make sure you do not have any files on it before you begin, because this process will delete all the contents of the drive. Download the old macOS Sierra Once downloaded, open the. We will need that in the next step. I used the app Install Disc Creator. Be sure to select the correct USB drive from the drop down! Once the Install Disc Creator is done it might take some timeit will show you a dialog box saying the install drive has been made.

    Close the app. Let the USB drive stay in your computer. When you find it, delete it. Download the new version of macOS Sierra from the link above. This is what we need to overwrite the Contents folder currently on the USB drive. Now navigate install the USB you created. I have Sierra, I downloaded the sierra OS link above…now what??

    I set the year to using 18 Aug. I had same problem Mojave installer damaged…. You must have an admin privilege. Then double click installer, and it worked. I am not sure if this work for everybody. I have tried to fix this problem by correcting the time during mojave installation. But it fails to me. I have downloaded ios many times. I reached this website and fixed the problem. I have a 10.0.2330.15693 the Terminal command for changing the date works for X and earlier, it does not fix the issue with this Mojave installer.

    I cannot move up to This also worked for me! Appreciate the terminal code here. The time change allowed me to get back into the installer again. Not only that, checking InstallESD. So I tried all three of those App Store links, and all 3 error. Yet all the other links in the App Store work fine. The other unofficial copy is to set the clock back to when the system software release was, usually like a year prior or whenever before the certificate expired. Do a search in the finder for Mojave.

    Looks like SmartMask killing the older MacOS. What if my iMac is not compatible with Catalina? How to fix this? Same error message in Terminal when trying to create a USB installer from the file downloaded from the Sierra link provided. No problem creating the same with El Capitan installer file. Also got error when trying to build a Sierra installer with Install Disk Creator app.

    Had the same problem. Here is the fix: Fist you need to turn Mac the WiFi. Then the Terminal app. Rich, thank you so much! Your fix worked for me as well. Was having the same issue re-installing macOS For Sierra on an iMac that had an issue updating its firmware. Went to suggested app store link for latest AKVIS installer. Another example of Apple not caring about longtime users: Avid, one of the standard of the postproduction industry that uses Mac based OS software has gone out their way to warn ProTools 12 users that Catalina will not work with their new OS.

    Not sword about this from Apple. Soooo True, I got burned on the catalina update. Still have some files on that drive Macos would love to get off. I updated windows with caution and only after a year or 2. No Way am I updating Mac again without the same caution and delay. It works. I have to imagine there are probably hundreds of thousands of bootable macOS USB installers and macOS installer applications out there, for IT admins, personal use, et al.

    Does the old trick of just temporarily changing the date from the command line using date or similar not still work? Some say that works for using boot drives but then the Mac reboots and connects to the internet will it be a problem? I downloaded the new ones, and they say they are damaged too. How annoying. What is Apple doing with the Mac? If necessary, just stay disconnected from the internet until the install from flash, HD, etc is completed.
