We know that it is not a curiosity for many, but last day I was wondering, "how long has it been since I no longer reinstalled the operating system on Mac?"
Normally, the MacOS operating system does not have to be reinstalled very often. Compared to other operating systems, macOS is very stable and access to the system's central files is very difficult. In addition, the installed applications interact only with the core files, which means that the OS is less likely to be severely affected, so it will need to be reinstalled,
Upgrades again are not a problem. There are users who have made some major upgrades to the MacOS version without doing a reinstall from scratch. That translates into years.
If you are curious to see how long you have installed the operating system on your Mac, you should follow some simple steps in the following tutorial:
1. Open the utility "consul". (Cmd + Space type "Console" → Enter).
2. In "Console" we go to the bar on the left to "Log Reports", Then in the right files we search and select"install.log"
In this file, "install.log" keeps all the data related to the installation and uninstallation of components and applications on macOS.
3. Scroll to the first line of "install.log" and the first information from that line is the date when it started operating on the system. Date of installation of the operating system.
It is good to follow the operation that was performed at that first time displayed in "install.log". If you have used "Clean Mac" programs, most of the time they will delete the system logs, and the recorded date will not be that of the MacOS system installation.How to find out the date when the operating system was installed on the Mac
