Starting in Android 8.0, Android devices use randomized MAC addresses when probingfor new networks while not currently associated with a network. In Android9, you can enable a developer option (it'sdisabled by default) to cause the device to use a randomized MAC addresswhen connecting to a Wi-Fi network.
2 days ago In addition to Windows and Linux machines, a new variant of the malware now targets Mac and Android devices. A new variant of the InterPlanetary Storm. Older Android devices have a USB Storage Mode that can be activated by plugging your device into your Mac, pulling down the notification shade, and tapping on the USB notification.
Pages for mac os x 10.11.6. In Android 10, MAC randomization is enabled by defaultfor client mode, SoftAp, and Wi-Fi Direct.
MAC randomization prevents listeners from using MAC addresses to build a historyof device activity, thus increasing user privacy.
Additionally, MAC addresses are randomized as part ofWi-Fi Aware andWi-Fi RTT operations.
To implement MAC randomization on your device:
Work with a Wi-Fi chip vendor to implement the following HAL methods:
IWifiStaIface#setMacAddress: Configures the MAC address of theinterface. The default implementation brings the interface down, changesthe MAC address, and brings the interface back up.
IWifiStaIface#getFactoryMacAddress: Gets the factory MAC of
ISupplicantP2pIface#setMacRandomization: Sets P2P MAC randomizationon/off in the supplicant.
truein the Settings
config.xml(this can be done in a devicecustom overlay).
- This flag is used to control whether client-mode MAC randomization isenabled.
truein the Settings
config.xml(this can be done in a devicecustom overlay).
- This flag is used to control whether Wi-Fi direct MAC randomization isenabled.
Test your implementation using the methods described inValidation.
The System UI must:
- Have an option to enable or disable randomization for each SSID.
- Have MAC randomization enabled by default for all newly added networks.
Use thereference implementation of Settings UI to implement new prompts.
Devices running Android 9 or lower might not havesupport for Wi-Fi MAC randomization. When upgrading such devices to Android10, the Wi-Fi MAC randomization feature can be disabledby setting the
WIFI_HIDL_FEATURE_DISABLE_AP_MAC_RANDOMIZATION flag to true inthe Wi-Fi vendor HAL make file.
To validate that the feature is working as intended, run both an integrationtest (ACTS) and a manual test.
To run an integration test, use the ACTS file,
WifiMacRandomizationTest.py, located in
tools/test/connectivity/acts/tests/google/wifi, to verify that the device usesthe randomized MAC address and correctly stores the randomized MAC address foreach network.
To run a manual test:
- Verify that MAC randomization is enabled on the device by checking that
config_wifi_connected_mac_randomization_supportedis set to
truein thedevice overlay.
- Connect to a Wi-Fi network.
- Tap the network to go to the Network details page. Verify that MACrandomization is turned on. Verify that the MAC address displayed is arandomized MAC, which has the locally generated bit set to 1 and themulticast bit set to 0.
- Turn MAC randomization off. Connect to the same network and verifythat the factory MAC is being used.
- Delete the network by tapping Forget on the Network details page.
Connect to the same network and verify that the same randomized MACaddress is being used.Note: Randomized MAC addresses are generated per SSID and are persistent.
To test MAC randomization on a pre-Android 10 device(capable of supporting MAC randomization) upgrading to Android10 or higher:
- Have at least one saved network on a device runningAndroid 9 or lower.
- Flash the Android 10 system image.
- In the Wi-Fi picker, verify that MAC randomization is turned off for allsaved networks.
- Turn MAC randomization on. Connect to the same network and verifythat the randomized MAC is being used.
Just plugged in a USB cable to get your Android phone or tablet connected to Mac, but nothing happened? That's true. Mac can't detect and recognize Android phone or tablet, let alone mount it as an external hard drive. In case like this, is it possible to transfer music, playlists, movies, photos and other files to and from your Android phone or tablet on Mac? How can you do it?
Well, to use Android on Mac, you can draw support from some third-party tools. Here are 3 of them: Wondershare TunesGo for Android, Android file transfer and Samsung Kies for Mac. In the part 1, I'd like to introduce the 3 software to you in details.
Part 1. 3 Software to Easily Connect Android to Mac
1. Wondershare TunesGo for Android (Mac)
Just jump ship from iPhone, iPad or iPod to an Android device, like Google Nexus 5, but have stored tons of songs, movies in iTunes which you don't want to leave behind? Like using iTunes to manage all your media files and eager to import playlists and videos from your Android device to it for playing? If that's what you want, Wondershare TunesGo for Android (Mac) is the best software for you. It's easy-to-use software, which lets you sync media files between iTunes/Mac and Android device without any hassle.

- It's not free.
2. Android file transfer
Android file transfer is created by Google, mainly used for you to manage your Android device on Mac freely. It can mount your Android device as an external hard drive, so you can transfer data from Android to Mac and vice versa.
- Mount your Android device as an external hard drive.
- Open any folder or file saved on the SD card of your Android device.
- Transfer music, video, photos and document files to and from Mac.

Part 2. Step-by-step Guide for USB Tethering of Android to Mac
You can tether your Android device with your Mac and for that you will have to use third-party application. Here I used HoRNDIS as the third party application. You can download the latest version of HoRNDIS.
After downloading it, you should install it on your Mac and then connect your Android phone to the Mac using data cable. Now from the notification menu enter Settings on your android device.
Then go to Wireless & Networks on your device as shown on the left side of the above picture where you will have to touch on Tethering & Portable Hotspot. Then a new menu will appear as the picture on right side. As shown there Select USB TETHERING and then your Android device will be tethered with Mac. Remember, you must be connected to a data or wifi network to make this work.
