Which camp are you in? Are you completely happy or would you consider switching?
That's what I did a fortnight ago, purchasing my first Mac after decades of using Windows. The initial learning curve wasn't terribly steep since the differences between OS'es (coming from Win10) aren't as dramatic as they once were. Now neck-deep in the Apple ecosystem, I don't see myself going back.
I think building a fanbase on social media
https://www.heyday.net/blog/how-to-build-a-fanbase-on-social-media-heyday-tips is a great way to promote your brand, connect with your audience, and grow your business. I use Instagram as my main platform, because it's the most popular among artists and art buyers. I post high-quality photos and videos of my work, behind-the-scenes, and events. I also interact with other artists and potential customers, and use relevant hashtags to get discovered. One of the tools that helps me a lot with my social media strategy is my Macbook. It's fast, reliable, and easy to use. I can edit my photos and videos, create engaging content, and manage my accounts on different platforms. I also love the design and the battery life of my Macbook. It's the best laptop for creative professionals, in my opinion.
