Work From Home, Study From Home, covid-19 changed your life. Everybody needs stable, high-speed Wi-Fi at home.

For people who start to work from home and study from home, you might also want to ask these questions. Here is the answer to these questions. With this article, you can build stable, high-speed Wi-Fi in your home. How to test Wi-Fi speed on Mac? How to test Wi-Fi strength? How to test Wi-Fi stability? How to test Wi-Fi speed on iPhone? How to test Wi-Fi signal strength on iPhone? How to check your internet speed on Mac? How to make your internet speed faster? The covid-19 changed the lifestyle of everybody in this world. So everyone needs a stable, faster internet speed now. When you buy the internet provider service from your ISP, they will provide the bandwidth package for you. Choose the one which might suit your request. I would suggest you choose the most considerable bandwidth you can afford.

Test your Internet Speed

The internet speed includes three key parameters, with these three key parameters (Download, Upload, Latency). You can know your network's quality, giving a general idea of the network.

  1. iWifi- speed & signal test, a professional Wi-Fi speed test, Wi-Fi Scanner, and Wi-Fi Explorer. For the technical guy, you should try this one. You also can try the lan device scanning feature to find all the devices in your network.

BTW, they have the iOS version. Also, the iOS version provides the AR Wi-Fi Map feature, and you can build your Wi-Fi signal map based on the app with your iPhone or iPad.

  1. speedtest.net by OOKLA is a very famous internet speed test vendor; with thousands of testing servers, it provides the most accurate internet speed result. With the result, you will know the quality of your Wi-Fi, your ISP service, and your router.

  1. Fast.com is the internet speed test website that NETFLIX powers. It helps you to know your internet speed to NETFLIX. Suppose you want to watch a streaming video from Netflix. In that case, this website will help you to understand which video quality you can watch on Netflix.

Wifi Scanner and Explorer

If you are a tech guy, testing your network speed is just a piece of general information, you might want to know more. It would help if you had the below tools on your Mac.

  1. iWifi- speed & signal test, a professional Wi-Fi speed test, Wi-Fi Scanner, and Wi-Fi Explorer. For the technical guy, you should try this one. You also can try the lan device scanning feature to find all the devices in your network.

    BTW, they have the iOS version. Also, the iOS version provides the AR Wi-Fi Map feature, and you can build your Wi-Fi signal map based on the app with your iPhone or iPad.

  2. WiFi Explorer, as this tool's name, only provides the explorer feature, so you also need to use another speed test app. This app only provides the Mac version.

Network Utility AirPort on macOS X

There are native tools that can also help check your Wi-Fi pieces of information. Click the Wi-Fi icon in the status bar with the option key pressed. Then you will see detailed information on current Wi-Fi. And you can click the "Create Diagnostics Report" menu to have a WirelessDiagnostics report file. You also can find the Network Utility with Finder -> Application -> Utilities. It is not available in Big Sur.

Conclusion

Still, many facts might affect your Wi-Fi internet speed, the apps running on your Mac or your iPhone, your router setting, and your bandwidth from your ISP. Plenty of Mac and iPhone tools can help you check your internet speed. There is always one thing that might resolve 80% of the issue. Like what is said in the IT crowd, "Have you tried turning it off and on again?"

Mac System Data Exceeding 200GB? Here’s How to Actually Clear It — A Deep Dive with Heavy Keynote Usage and Time Machine as Examples I. Problem Overview After long-term use, some macOS users discover that “System Data” in Storage Settings grows abnormally large. Common symptoms include: System Data occupying 200GB or more https://cdn.okaapps.com/resource/图2.webp No corresponding files can be located in Finder Deleting caches or log files has little effect Third-party cleaning tools are ineffective Uninstalling and reinstalling apps (such as Keynote) does not help Even after reinstalling macOS, the issue reappears after some time This problem is especially common among heavy productivity users, such as those working extensively with Keynote, Final Cut Pro, or design tools. II. Commonly Tried but Ineffective Solutions Users typically attempt the following methods, most of which fail to solve the problem at its root: Manually deleting directories such as ~/Library/Caches and ~/Library/Logs Using third-party cleaning tools like CleanMyMac or similar utilities Uninstalling and reinstalling Keynote Reinstalling macOS via “Reinstall macOS” These approaches are limited because they do not address the real sources behind System Data inflation. III. What Exactly Is “System Data”? It is important to understand that: System Data is not a real folder, but rather a collection of data that macOS cannot accurately categorize. System Data may include, but is not limited to: macOS system temporary files Application and system caches Portions of the user Library (~/Library) Files Spotlight cannot classify Large resource files inside application packages Local caches from cloud services (such as iCloud or OneDrive) iPhone / iPad backup files Residual data from deleted user accounts Time Machine local snapshots As a result, System Data cannot be reliably inspected or reduced through simple cache deletion or Finder-based browsing. IV. Key Cause #1: Time Machine Local Snapshots Consuming Disk Space How Local Snapshots Work Even when no external drive or NAS is connected, macOS will: https://cdn.okaapps.com/resource/图3.webp Create a Time Machine local snapshot every hour Retain snapshots from the last 24 hours by default If the backup destination remains disconnected, keep local snapshots associated with the most recent full backup These snapshots: Are based on the APFS file system Do not appear as regular files Are entirely counted under System Data In some cases, local snapshots can consume tens or even hundreds of gigabytes. https://cdn.okaapps.com/resource/图4.webp Why They Sometimes Cannot Be Deleted When Time Machine uses a NAS or network storage device as its backup destination, the following situations may occur: The NAS was previously disconnected The network path or IP address changed The backup was not re-“claimed” by the system As a result, macOS may treat these snapshots as belonging to an unreachable backup destination, leading to: tmutil deletion failures Errors such as Stale NFS file handle Snapshots that cannot be reclaimed, causing persistent disk usage V. Key Cause #2: How Keynote and Similar Apps Amplify System Data Keynote itself is not malfunctioning, but its design inherently amplifies System Data usage: Keynote files are actually packages containing large numbers of resources These may include: High-resolution images Embedded videos Fonts Animation and transition assets Spotlight sometimes fails to correctly classify these resources, causing them to be grouped under System Data. For users who frequently create large, media-heavy presentations, steady growth in System Data over time is expected. VI. Effective Solutions (Prioritized) Solution 1: Verify and Restore Time Machine Backup Status (Recommended) Open Disk Utility From the menu bar, select Show APFS Snapshots Select the system Data volume Check whether a large number of Time Machine local snapshots exist If using a NAS as the backup destination: Reconnect the NAS Select the original backup in Time Machine settings Follow the prompts to claim the existing backup Once the backup relationship is properly restored, macOS can automatically manage and reclaim snapshot space. Solution 2: Use Disk Analysis Tools to Identify Real Space Usage It is recommended to use tools that analyze disk usage without automatically deleting files, such as: GrandPerspective EtreCheck The goal is to identify: Which files or directories consume the most space Whether disk usage is abnormally concentrated in specific areas Avoid relying on “one-click cleanup” tools. Solution 3: Check for Residual Data from Old User Accounts If the device previously: Had multiple user accounts Removed accounts without deleting their home folders Then old home directories may still exist and be counted as System Data. Solution 4: Rebuild the System Environment Completely (Last Resort) When System Data usage becomes severely unmanageable and no clear source can be identified, the only definitive solution is: Fully back up all current data Erase the disk and reinstall macOS During setup: Migrate only the user account Do not migrate system settings, applications, or Library data This approach completely removes legacy data structure issues. VII. Long-Term Prevention Tips (for Keynote and Content Creators) Archive older Keynote projects to an external drive or NAS Avoid storing large volumes of presentation files locally for long periods Keep the Time Machine backup destination consistently available Avoid third-party tools that perform automated “system-level cleaning” Periodically monitor disk usage with analysis tools VIII. Conclusion Abnormally large macOS System Data usage is rarely caused by a single cache or log issue. Instead, it is typically the result of Time Machine local snapshots, application package resources, and inherited historical data structures working together. Only by understanding what System Data actually contains—and addressing the root causes—can disk space issues be resolved effectively and long-term.
