Apple will release a new version of Mac OS 10.15 “Catalina” that will only run 64-bit software. The current Mac OS 10.14 (Mojave) will be the last version capable of running 32-bit applications.

Before you upgrade to Catalina I recommend to first verify what app’s will stop working after you install Catalina. Rolling back to the previous installed version of the Mac OS will be a very hard and costly to reverse.

The easiest way to verify the compatibly of your current setup is to install the free Go64 app from St. Clair Software. The app Go64 identifies the apps on your Mac that are still 32-bit so you can plan to update or replace them in the near future.

To completely remove redundant software from your Mac I recommend CleanMyMac. This is a great application to easily uninstall any software you want to remove from your Mac including all the hidden files that clutter our system. It is also an excellent maintenance tool that will help your Mac running smooth including general malware removal.

Many people use Wi-Fi to connect to the internet when traveling, sometimes it doesn’t want to work correctly.

Remove the unwanted Wi-Fi network by opening Wi-Fi in the Settings menu. Moreover, then tap the “I” symbol to the right of the network and choose “Forget This Network*. To avoid a constant disruption to connect to a Wi-Fi network, you happen to pass by. You should disable the popup message to join a Wi-Fi network by turning off “Ask to Join Networks.”

Sometimes a Wi-Fi connection needs a bit of help to make it work. Return to Wi-Fi in the Settings menu, tap the “I” and select “Renew Lease.” Besides, you can manually enter a DNS server address. DNS is responsible for directing your web browser to the IP address of the website you want to visit. Some DNS servers are better than others. It is worthwhile to change the DNS server address by tapping the “Configure DNS” section and change from Automatic to Manual. Remove any existing t DNS servers and search domains. Add a server electing the green “+” sign and use one or more of the following suggestions:

  • Google DNS
  • Google DNS
  • IBM Quad Nine fast & private
  • Cloudflare one of the leading web hosting service and is fast & private

Changing the DNS servers also helps to prevent the network operator of spying on your web browsing or redirect you to websites they want you to go. Better yet you can encrypt the DNS traffic with the app.

*Ultimately you can delete all Wi-Fi and BlueTooth setting in: Settings > General > Reset > “Reset Network Settings.

Never trust a strangers network, whether its a hotel, airport, coffee shop, or Air B&B. There is a chance that someone else on the network will see every website you visit and intercept the passwords you enter or might try to break into your computer.

The best solution is to use a trusted VPN service. This application will rout all your data through an encrypted tunnel to another location on the internet and will put many barriers in place to protect your location and privacy. Be careful about choosing a VPN provider since they can see all your traffic. I did the research and found that Nord VPN is one of the best out there. Currently they have a -75% Offer!

Millions of people have had access to their email compromised by someone gaining unauthorized access to their email account. Sometimes this goes unnoticed for a long time giving the bad actor to be the man in the middle or use your account to hide their tracks while defrauding others or start sending spam.

Usually, people only notice that their account has been compromised when their contacts complain of receiving spam. The man in the middle or illicit use of your email account is hard if not impossible to detect. We can block the unauthorized access to an email account by changing the password. Hopefully with a strong and unique password and enabling their 2 step verification/authorization.

Changing password is not enough to stop unauthorized use of your email address!

A smart hacker can set some simple rules in your email account to automatically process and forward email regardless of how often passwords are updated with strong ones. These filters continue to keep doing their job of the hacker well informed about emails flowing through your email account.

How to check your email account for unwanted email forwarding

Log into the web version of your email account. For example, etc. Open the filters page under settings. Verify that any “rules” or “filters” that might be present and delete anything suspicious to you. Just in case you are ever contacted by law in force not it wise to make a note of the settings or take a screenshot of any suspicious rule before deleting it.

To see the size of a specific file or folder, click it once and then press Command-I. To see storage information about your Mac, click the Apple menu in the top-left of your screen. Choose About This Mac and click the Storage tab. For Time Machine backups, it’s good to use a drive that has at least twice the storage capacity of your Mac.

In Disk Utility on Mac, you can erase and reformat storage devices to use with your Mac. Erasing a storage device deletes everything on it.

  1. If you have any files you want to save, copy them to another storage device.
  2. Open the Disk Utility app  on your Mac using one of the following methods, depending on the type of disk or volume you want to erase:
    • If you want to erase your startup disk or startup volume: Start up from macOS Recovery, then choose Disk Utility from the macOS Utilities window.
    • If you want to erase any other type of disk or volume: Double-click Disk Utility in the /Applications/Utilities folder.
  3. Choose View > Show All Devices.
  4. In the sidebar, select the storage device you want to erase, then click the Erase button .
  5. Click the Scheme pop-up menu, then choose GUID Partition Map.
  6. Click the Format pop-up menu, then choose a choose a file system format.
  7. Enter a name.
  8. (Optional) If available, click Security Options, use the slider to choose how many times to write over the erased data, then click OK.Secure erase options are available only for some types of storage devices. If the Security Options button is not available, Disk Utility cannot perform a secure erase on the storage device.Writing over the data three times meets the U.S. Department of Energy standard for securely erasing magnetic media. Writing over the data seven times meets the U.S. Department of Defense 5220-22-M standard.
  9. Click Erase, then click Done.

Proceed based on whether you’re erasing your startup disk or some other disk. Your startup disk is the disk (volume) that your Mac started up from. By default it’s the disk built into your Mac, named Macintosh HD. If you’re selling, giving away, or trading in your Mac, you should erase your startup disk.

  1. Start up from macOS Recovery.
  2. Select Disk Utility from the Utilities window in macOS Recovery. Then click Continue.

  3. Make sure that the sidebar in Disk Utility shows the name of your startup disk. The volume representing your startup disk is Macintosh HD, unless you renamed it. Don’t see it?
  4. Look for a ”Data” volume with the same name, such as ”Macintosh HD – Data.” If you have such a volume, select it. Then choose Edit > Delete APFS Volume from the menu bar, or click the remove volume button (–) in the Disk Utility toolbar. Do the same to delete any other volumes you might have on your startup disk—except the volume named Macintosh HD.

  5. Now select Macintosh HD.
  6. Click the Erase button or tab, then complete these items:
    • Name: Enter a name that you want the volume to have after you erase it, such as Macintosh HD.
    • Format: Choose either APFS or Mac OS Extended (Journaled) to format as a Mac volume. Disk Utility shows the recommended Mac format by default.
  7. Click Erase to begin erasing. You might be prompted to enter your Apple ID.

  8. When done, quit Disk Utility to return to the Utilities window.
  9. If you want your Mac to be able to start up from this volume again, choose Reinstall macOS from the Utilities window.

You can erase a disk or volume at any time, including in circumstances such as these:

  • You want to quickly and permanently erase all content from your Mac and restore it to factory settings, such as when you’re selling, giving away, or trading in your Mac.
  • You’re changing the format of a disk, such as from a PC format (FAT, ExFAT, or NTFS) to a Mac format (APFS or Mac OS Extended).
  • You received a message that your disk isn’t readable by this computer.
  • You’re trying to resolve a disk issue that Disk Utility can’t repair.
  • The macOS installer doesn’t see your disk or can’t install on it. For example, the installer might say that your disk isn’t formatted correctly, isn’t using a GUID partition scheme, contains a newer version of the operating system, or can’t be used to start up your computer.
  • The macOS installer says that you may not install to this volume because it is part of an Apple RAID.

If you want to change the format, answer these questions:

Are you formatting the disk that came built into your Mac?
If the built-in disk came APFS-formatted, don’t change it to Mac OS Extended.

Are you about to install macOS High Sierra or later on the disk?
If you need to erase your disk before installing High Sierra or later for the first time on that disk, choose Mac OS Extended (Journaled). During installation, the macOS installer decides whether to automatically convert to APFS—without erasing your files:

  • macOS Mojave or later: The installer converts from Mac OS Extended to APFS.
  • macOS High Sierra: The installer converts from Mac OS Extended to APFS only if the volume is on an SSD or other all-flash storage device. Fusion Drives and traditional hard disk drives (HDDs) aren’t converted.

Are you preparing a Time Machine backup disk or bootable installer?
Choose Mac OS Extended (Journaled) for any disk that you plan to use with Time Machine or as a bootable installer.

Will you be using the disk with another Mac?
If the other Mac isn’t using High Sierra or later, choose Mac OS Extended (Journaled). Earlier versions of macOS don’t mount APFS-formatted volumes.

Choosing name, format, and scheme in Disk Utility

Disk Utility tries to detect the type of storage and show the appropriate format in the Format menu. If it can’t, it chooses Mac OS Extended, which works with all versions of macOS.
