Philip Joseph Adams, (born: April 21, 1994), better known online as OSFirstTimer, is an Australian YouTuber who makes operating system videos.
About[]
The channel has Philip's family (his mom, dad and younger sister) test out various operating systems. In every episode, five basic tasks are used to complete on these operating systems.
The original aim of OSFirstTimer was to find the best operating system which eventually turned out to be Arch Linux with the KDE desktop environment installed; it was given the unofficial name of 'The Diana Perfect OS' as Diana (Philip's mum) personalized it to her liking. The worst OS was declared as MS-DOS in the 'Top 3 Worst and Best Operating System User Interfaces' video.
After the best and worst operating systems were decided, the channel then solely focused on exploring operating systems in general; this was expanded upon with the OSFirstTimer Advanced series.
While the channel was inactive for over a year because of renovation work Phil uploaded a video on December 9, 2019 explaining how VFR (Variable Frame Rate, where the frame rate changes to record as the device can handle at the time) was making it hard to edit as the audio and video were getting constantly unaligned. When putting the files through HandBrake it fixed the issue but Sony Vegas wouldn't accept the files, but while recording visuals for the video Sony Vegas accepted the files thus meaning the problem was fixed and editing of the video "Mum Rates Elementary OS 5 (2018) vs MX Linux 19 (2019)" was much easier.
He no longer uploads consistently due to the fact that he now has several day jobs. On May 12th, 2025, They announced that the Channel would be "disappearing again" indefinitely. however, one more video was announced to be uploaded later in 2025[1], which was uploaded on July 2nd. historically, the channel has had an every 3 day schedule.
