Rule summary
- Be civil: Please be kind to one another. r/mac is not a place for fighting. Insults will not be tolerated.
- Follow Reddiquette: Please click the link to read about Reddiquette. https://www.reddithelp.com/en/categories/reddit-101/reddit-basics/reddiquette
- No unrelated posts: Posts must be related to r/Mac, which means computers made by Apple. This is not a subreddit for iPhones, iPads, and other Apple products (with exceptions such as Mac displays). Posts unrelated to r/mac will be removed. Pictures of boxes are not related to r/Mac. Boxes for older Mac computers (PowerPC and older) are excluded from this rule.
- Flair your posts: Please flair your post appropriately. All posts that are not flaired are subject to removal.
- No promotion or advertising: Promotion or advertising is not allowed on r/mac. If your post, comment or username is found to be associated with a brand, product, or service, it will be removed. This rule includes anything you've made (e.g. wallpaper, app, blog post, video), free or paid.
- Only post pictures of your Macs on Fridays: Please only post pictures of your computers on Friday. This rule is based on UTC, so [check the day of the week in UTC before posting](https://time.is/UTC). This does not apply to Macs that were made over 10 years ago.
- Prohibition on Generative AI Content: All content must be primarily human-authored. Content may be removed under this rule at the discretion of the moderator team. reddit is not exclusively an English-language platform. You are welcome to post in any language. reddit provides in-app language translation, so there is no need to use a large language model to translate or reformat your post or comment into English.
Works well
- A human-written post asking how other Mac users handle a specific macOS workflow problem, with no links and a flair added.
- A Friday photo of your Mac setup, posted only on Friday in UTC, with a flair and no promotional language.
- A text post sharing a non-promotional tip about an older Mac, over ten years old, that you still use for real work.
- A question about Mac displays, since the rules allow that as an exception to the no-non-Mac-products rule.
Avoid
- Promoting anything you made, even a free wallpaper, app, blog post, or video, because the rule No promotion or advertising bans it and will get your post removed.
- Posting pictures of your modern Mac on any day that is not Friday in UTC, since the rule Only post pictures of your Macs on Fridays will catch it.
- Posting pictures of Mac boxes unless they are PowerPC era or older, because the rule No unrelated posts treats box photos as unrelated.
- Sharing anything about iPhones, iPads, or other non-Mac Apple products, since the rule No unrelated posts will remove it.
- Using generative AI to write, translate, or reformat your post or comment, because the rule Prohibition on Generative AI Content bans it.
- Forgetting to add a flair to your post, because the rule Flair your posts says unflaired posts are subject to removal.
What r/mac Is For
This community is for everything related to Apple's Mac computers. The rules make clear that means computers made by Apple, not iPhones, iPads, or other Apple products, with exceptions such as Mac displays. People post here to talk about Macs, share Mac-related content, and ask questions about Apple computers.
Rules That Matter Before Posting
The rule that matters most for anyone doing marketing-adjacent work is No promotion or advertising. It says that if your post, comment, or username is associated with a brand, product, or service, it will be removed, and it explicitly includes anything you have made, free or paid. The rule No unrelated posts keeps the room focused on Apple computers, not iPhones or iPads, and it bans pictures of boxes unless they are PowerPC era or older. The rule Flair your posts means every post needs a flair or it is subject to removal. The rule Only post pictures of your Macs on Fridays limits modern Mac photos to Friday in UTC, with an exception for Macs over ten years old. The rule Prohibition on Generative AI Content means your post must be primarily human-authored, and you should not use a large language model to translate or reformat your text.
What To Post
A good post here is a genuine, human-written contribution about a Mac computer, with a flair added, and with no trace of promotion in the post, comment, or username. You could share a real question about using a Mac for your work, a tip about macOS that helped you, or a story about an older Mac you still rely on. If you want to share a photo of your modern Mac, wait until Friday in UTC. If your Mac is over ten years old, you can share it any day. Keep your username clean of brand references, because the promotion rule reaches usernames too.
What To Avoid
Avoid anything that looks like promotion or advertising, including links to your own app, blog, video, wallpaper, or service, because the rule No promotion or advertising will remove it and even your username can trigger removal. Do not post about iPhones, iPads, or other non-Mac Apple products, since the rule No unrelated posts will catch them. Do not post pictures of modern Macs except on Friday in UTC, and do not post pictures of Mac boxes unless they are PowerPC era or older. Do not use generative AI to write, translate, or reformat your post or comment, because the rule Prohibition on Generative AI Content bans it. Do not leave your post unflaired, because the rule Flair your posts says unflaired posts are subject to removal. Do not be uncivil, because the rule Be civil will not tolerate insults.

Can I post a photo of my Mac setup?
Only on Friday in UTC, and only if the Mac itself is the focus. The rule Only post pictures of your Macs on Fridays is based on UTC, and the rule No unrelated posts says box photos are not allowed unless the Mac is PowerPC era or older.
Can I post if my Reddit username includes my brand name?
Yes, as long as your username is not associated with a brand, product, or service. The promotion rule says usernames can trigger removal under the same rule.
Can I use AI to translate my post into English before posting?
No. The rule Prohibition on Generative AI Content says all content must be primarily human-authored, and it specifically calls out using a large language model to translate or reformat your post.
Can I post about an iPad app that works alongside a Mac?
No. The rule No unrelated posts says this subreddit is for computers made by Apple, not iPhones, iPads, or other Apple products, with exceptions such as Mac displays.
