I use a 2018 15" Macbook Pro from work. It's connected to a 27" 1440p 165Hz Dell monitor. Also connected to the monitor is a PC that I built myself with: a Ryzen 5600X CPU, an RX 6650 XT GPU, 32 GB of DDR4 RAM encased in a nice, white Lian Li Lancool 206 case that has way better airflow than my previous case. This choice was made with the help of Gamers Nexus YouTube channel.
The keyboard is a Yunzii AL71 mechanical keyboard that sounds gorgeous when typed on; I would never go back to mushy silicone dome keyboards. I use a Razer Basilisk V3 PRO as my mouse. I like the precision that high dpi gaming mice have, and, in this case, the freespin scroll wheel. Under it I have a cheap Steelseries mousepad that's a bit old but it's still in good shape. For sound I use a pair of Audio Technica ATH-M50XBT headphones and as input, a Genesis Radium 300 XLR microphone, connected through a Focusrite Scarlett Solo audio interface. I also have a pair of Earfun Air Pro 4 earbuds, that are ok for their price but wouldn't recommend. The Audio Technica I would highly recommend.
My phone is an iPhone 15 Pro with a black Decoded leather case. I'm trying to keep it at least for 4 years.
My main design software is Figma, but I'm looking into Penpot as replacement. For other design work I use Affinity Design and Affinity Photo, and for editing photos I use Capture One; I'm glad to be off Adobe ☠️. For design hand over I use Zeplin (but Penpot could do this job as well), and for projects organization / to do lists I use Agenda.
My browser of choice is Zen which is based on Firefox. For code editing I use Visual Studio Code (switched from Pulsar because it was slow), iTerm for terminal, Bitwarden for password management, Spotify for music streaming, Pocket Casts for podcasts. I edit my woodworking videos using DaVinci Resolve. IINA is my preferred video player on the Mac, and VLC on the PC. OBS is what I use for screen recording.
For local server I use MAMP. For email I use Proton Mail (not completely off Gmail tough) and Proton Drive for cloud storage. Signal is the best messaging platform and I convinced my partner and my friends to use it. But I also have Whatsapp for family members and others. Simplenote for other notes and Any.do for shopping lists mainly as I can share it with my wife.
