Slack Green 블로그

Yes. When you edit a Slack message, everyone sees the new text with an (edited) label, and nobody gets a new notification. Coworkers cannot view the old version, but notifications, apps in the channel and a save-edits retention setting can keep it. What others see, what admins can see, and how to fix a typo without a label.

A Mac that keeps going to sleep usually has a short display timer: when the display turns off, the Mac sleeps about a minute later. On battery the default can be 2 minutes. How to read the exact reason in pmset -g log, the System Settings that control it, and Terminal commands for when you need the Mac awake.

You can't. Google Chat has no last seen or last active time. It shows only whether someone is active now, idle for 5 minutes on a computer, or away, and in direct messages it shows how far they have read. The clues you can use, what each one proves, and what Workspace admins see that coworkers do not.

Google Chat has no invisible mode, but Set as away gives the same result: your status shows Away, which is also what people see when you are offline, and messages keep arriving. Steps for Gmail, the Chat app and phones, what others can still see, and how blocking and calendar status change it.

Do not disturb in Google Chat mutes Chat notifications on every device until the time you choose, and shows coworkers a red icon with how long you paused them. How to turn it on and off on a computer and a phone, how to schedule it, what others see, and why some bot messages still come through.

Slack has no built-in be right back status. Type your own, such as BRB, back in 15, pick an emoji, and set Remove status after to 30 minutes so it clears on its own. Lines to copy, a one-click setup for next time, and why your dot still turns away.

Your employer can usually place your work laptop only in a city, from the IP address in sign-in and VPN logs. Two IP lookups we ran on 2 November 2026 put the same Mac 3.7 km apart. Most laptops have no GPS; Intune can locate managed Windows laptops.

Caffeine is a free, open-source menu bar cup that keeps a Mac awake with one click. Amphetamine is a free App Store app with triggers, schedules and a closed-lid mode. We checked both on macOS 26.5.2: versions, settings, and what each holds in pmset. Which to pick, and what neither one does.

Zoom has no Appear offline or Invisible status. Your contacts see Offline only when you are not signed in to any Zoom app, so the way to appear offline is to quit the desktop app and sign out of the mobile app. The steps for each device, what to use when you need to stay signed in, and what your admin can hide.

sudo pmset -a disablesleep 1 stops all system sleep on a Mac, lid closed included, and sudo pmset -a disablesleep 0 turns normal sleep back on. How to check whether it is on, why it outlives a restart, and the pmset and caffeinate commands to use instead.

Your employer cannot read WhatsApp Web messages off the office network, because they are end-to-end encrypted. On a work laptop with monitoring software, screenshots and keystroke logs can still show every chat you open and every message you type. What each method sees, and how to keep WhatsApp private at work.

Slack이 브라우저에서 열리는 것은 링크가 app.slack.com으로 가거나, 브라우저가 앱으로 넘기지 못할 때입니다. Mac에서 두 종류의 링크를 시험한 결과와 slack:// 연결을 확인하는 방법을 정리했습니다.

@here는 지금 활성인 멤버에게만, @channel은 채널의 모든 멤버에게, @everyone은 일반 채널에서 워크스페이스 전체에 알림을 보냅니다. 실제 Slack에서 해 보니 "채널에도 보내기"를 체크해도 스레드에서는 셋 다 알림이 가지 않았고, 일반 채널이 아닌 곳에서 입력한 @everyone은 그냥 글자로 남았습니다.

Slack에서는 메시지 스크린샷을 찍어도, 텍스트를 복사해도, 이미지를 저장해도 누구에게도 알림이 가지 않습니다. Mac 앱(Slack 4.52.171부터 4.52.182까지)과 웹 클라이언트 코드를 검색해 스크린샷 감지 기능이 없다는 것을 확인했습니다. Enterprise 관리자가 대신 막을 수 있는 것과 기록할 수 있는 것도 정리했습니다.

caffeinate는 Mac을 깨워 두는 macOS 기본 명령어입니다. -d는 화면, -i는 잠자기를 막고, -t로 시간을 정하며 Ctrl+C로 멈춥니다. 옵션과 예제, caffeinate로 Slack 활성 상태가 유지되지 않는 이유.

Slack 사이드바 섹션은 유료 플랜에서 쓰는 채널과 DM의 개인 폴더입니다. 무료 플랜 메뉴를 확인해 보니 섹션 만들기에 PAID 표시가 있었고, 기본 필터인 "활성만"은 30일 동안 움직임이 없는 채널을 숨겼습니다.

KeepingYouAwake is a free, open-source menu bar switch that runs Apple's caffeinate for you. Amphetamine is a free App Store app with triggers, schedules and a closed-lid mode. Pick KeepingYouAwake for one click and Homebrew, Amphetamine for automation. Neither keeps Slack or Teams active.

A Citrix session can end from four different timers: Windows locking inside the virtual desktop, the Citrix session idle timer, the Citrix Gateway session time-out, and the StoreFront web page timeout. Only input from your own device into the Citrix window resets them. How to tell which one hit you and what keeps each one quiet.

Google Chat shows you Idle after 5 minutes without activity in Gmail or Chat on a computer, and Away once you have been idle for more than 10 minutes. Losing your connection or a sleeping computer shows Away at once. Neither timer can be changed, by you or by a Workspace admin.

Don't Sleep is a free, portable 267 KB Windows app from SoftwareOK that blocks standby, hibernate, the screen saver, log off and shutdown while it runs, with a timer and CPU or network rules. Where to get the real one, what each option does, the command line for a batch file, and what it does not do for Slack or Teams.

14 Chrome extensions for remote work, grouped by the job: async video, meetings, focus, writing, passwords, tabs, screenshots, time tracking and keeping the screen on. Each checked on the Chrome Web Store, with user counts, cost, and the extensions to avoid on a work laptop.

No. A Zoom meeting host cannot read private messages between two other participants, even in a saved chat. Zoom Team Chat on a work account is different: the company owns it, and admins can archive and search it. What hosts, admins and your manager can each see, with the chat permission labels from Zoom's own web client.

Slack has no alert for when a coworker becomes active. No preference, Workflow Builder trigger or profile button does it. You can watch their green dot, send a message they will see when they return, or run a short script that checks users.getPresence every minute and DMs you.

Outlook shows your Microsoft Teams status, so it turns to Away, a yellow clock, after about 5 minutes without keyboard or mouse input, or at once when you lock the computer. Outlook has no idle timer of its own. Why it can show Away while you work, and what changes it.

Run pmset -g in Terminal. The sleep line names every app that is keeping your Mac awake right now, such as a browser tab playing audio, a Zoom call or Amphetamine. How to read it, the settings that keep a Mac awake on purpose, and how to find what wakes a sleeping Mac at night.

A white circle with a green outline and a green check on Microsoft Teams means the person is Available but has Out of office on. They are using Teams while their automatic replies or an out-of-office calendar event is active. A solid green circle with a white check is plain Available.

Cisco Jabber sets you to Away after 15 minutes without input and when you lock Windows. Where to raise the timer, how to turn off away-on-lock, the jabber-config.xml parameters IT controls, and why Jabber still shows In a meeting or Offline.

Teams keeps showing you Offline when Appear offline is still on, when no device is signed in, or when the app has no presence value yet: the Teams code draws that missing value with the same grey Offline badge. A fix for each cause, and why other people may see you Offline.

By default, yes. Microsoft says anyone in any organization using Teams can see your presence, and Last seen is part of the Away status. Your admin decides who outside the company sees it: all organizations, only some, or none with privacy mode. What guests, federated contacts and personal Teams accounts see, and how to check your company's setting.

Windows and Mac jiggler apps do not run on a Chromebook, and a Chrome extension cannot move the real pointer. What works: a USB mouse jiggler, a turntable mouse mover, or no jiggler at all, because ChromeOS can keep the display on by itself. Setup for each, and what they do for Teams and Slack.
