![]() ![]() One major lesson we learn from the COVID-19 coronavirus story, is that centralised workplaces are unprotected against vis major scenarios. If you took it to an official Apple certified repair center, you most probably ended paying for a new motherboard.īy the symptoms it looks like Big Sur is doing it again.Īs always: do not even think of upgrading to Big Sur before spring until all major bugs are resolved, and make sure to read our previous post on this topic as a Golden Rule. Previously Catalina damaged the T2 chip on noticeable number of newer machines, making it impossible for the Mac to charge itself, but even on older ones without the T2 it managed to corrupt the SPI ROM that needed to be reflashed – this is not something an official repair center offers as it requires soldering – a technique only independent repair shops do. Some Mac owners are getting an appointment for January already, however it’s not even December yet.Īt first it seamed that Big Sur is bricking MacBook Pros that are manufactured between 2013-2014, but there’s a report from 2016 MacBook Pro and iMac users too. Why am I saying it’s a Christmas present?īecause of Covid both official and independent repair stores are overcrowded, and there’s a waiting line of 1-1,5 month at many places. This year Apple engineers have prepared a special Christmas present for some users: the installation fails at some point, and your Mac shows no sign of life anymore – it’s bricked. Now if you have 15 years of email on your computer, not even God can find those randomly missing emails. Last year when Catalina was released, the initial builds had a huge flaw – many users have experienced loss of mail data who used the Mail.app that’s part of the macOS. Sudo plutil /Library/LaunchDaemons/ĭo you need some excitement and potentially brick your Mac for good? And make sure to check it with plist utility: Library/Preferences/SystemConfiguration/.plistĪt the end your plist should look like this:Īs a best practice, enter the code manually, do not copy-past as it might contain some invisible characters that can make the plist unusable. Library/Preferences/SystemConfiguration/ist here we are telling launchctl to wait for changes in the provided locations – that actually reflects the initialisation of network interfaces What you may want to fix in your existing plist are the following changes:Īnd add these lines. plist will be loaded by the launchctl process upon startup.Īpple does not provide a way to delay a startup of a process via launch daemon, but we can tell launchctl to wait for the network interfaces to complete the initialisation and then start up the vpnd binary that acts as a VPN server. If you have your self made plist, this is the location to put. Applications/VPN\ Enabler.app/Contents/Resources/VPNStuff/… The startup of vpnd is managed by a plist file that VPN Enable copies from here: The reason vpnd daemon does not respond to a connection is that the process starts too early during the boot, before the network interface has been initialised. Sudo launchctl unload -w /Library/LaunchDaemons/ If you are using the VPN Enabler you have to launch it and click the ‘Restart VPN’ button, or simply issue this command via Terminal: plist files and VPN Enabler is that when the Mac that acts as a server is restarted, the vpnd process runs (we can see it in Activity Monitor), but you can’t connect to it and establish a VPN connection. The issue with both the publicly available. On newer OSes you may try the Open VPN Enabler for Catalina. You can create both manually, but it’s much easier to do it with a third-party app called VPN Enabler that works up to 10.14 Mojave. If you can’t connect to your VPN server upon startup, then read on.Īlthough Apple decided to abandon the Server.app and completely shut down internal efforts to provide a solutions that would help using a Mac as a server, macOS still comes with a built-in VPN server we can engage.īasically it needs two plists: one that contains the configuration including the DHCP IP range etc., and the other one that is called by the launchctl daemon and starts the vpnd command.
