Same issue here. Apple, please help! My Mac panics every time I try to run Visual Studio (on Windows, Parallels Desktop) and try to debug an iOS app (which runs Xamarin on Mac = Xcode). The problem starts to occur since updating to XCode 12.5. macOS BigSur v. 11.3.1 (20E241) MacBook Pro (16-inch, 2019) 2,4 GHz Intel Core i9 8 core 64 GB 2667 MHz DDR4 Intel UHD Graphics 630 1536 MB "build" : "Bridge OS 5.3 (18P4556)", "crashReporterKey" : "c0dec0dec0dec0dec0dec0dec0dec0dec0de0001", "date" : "2021-05-13 14:30:41.34 +0000", "incident" : "D08D6DA6-633B-4F09-AF9F-A109EA4CBA9A", "kernel" : "Darwin Kernel Version 20.4.0: Thu Mar 4 23:34:36 PST 2021; root:xnu-7195.101.1~1\/RELEASE_ARM64_T8010", "macOSOtherString" : "\n In Memory Panic Stackshot Succeeded Bytes Traced 188132 (Uncompressed 474976) **\n", "macOSPanicFlags" : "0xc", "macOSPanicString" : "panic(cpu 6 caller 0xffffff801bdeba25): userspace watchdog timeout: no successful checkins from com.apple.logd in 120 seconds\nservice returned not alive with context : unresponsive dispatch queue(s): com.apple.firehose.io-wl \nservice: com.apple.logd, total successful checkins since load (3730 seconds ago): 362, last successful checkin: 120 seconds ago\nservice: com.apple.WindowServer, total successful checkins since load (3700 seconds ago): 358, last successful checkin: 120 seconds ago\nservice: com.apple.remoted, total successful checkins since load (3730 seconds ago): 372, last successful checkin: 0 seconds ago\n\nBacktrace (CPU 6), Frame : Return Address\n0xffffffc1ce71b670 : 0xffffff8018a8e02d \n0xffffffc1ce71b6c0 : 0xffffff8018bd48e3 \n0xffffffc1ce71b700 : 0xffffff8018bc4eda \n0xffffffc1ce71b750 : 0xffffff8018a32a2f \n0xffffffc1ce71b770 : 0xffffff8018a8d84d \n0xffffffc1ce71b890 : 0xffffff8018a8db43 \n0xffffffc1ce71b900 : 0xffffff801929d6f4 \n0xffffffc1ce71b970 : 0xffffff801bdeba25 \n0xffffffc1ce71b980 : 0xffffff801bdeb660 \n0xffffffc1ce71b9a0 : 0xffffff801921eede \n0xffffffc1ce71b9f0 : 0xffffff801bdeaa34 \n0xffffffc1ce71bb20 : 0xffffff801922911b \n0xffffffc1ce71bc80 : 0xffffff8018b80401 \n0xffffffc1ce71bd90 : 0xffffff8018a936ad \n0xffffffc1ce71be00 : 0xffffff8018a69c85 \n0xffffffc1ce71be60 : 0xffffff8018a812a2 \n0xffffffc1ce71bef0 : 0xffffff8018ba91fd \n0xffffffc1ce71bfa0 : 0xffffff8018a33216 \n Kernel Extensions in backtrace:\n com.apple.driver.watchdog(1.0)[57B278ED-0B7C-3544-9CFE-53963BB1DAF3]@0xffffff801bde9000-0xffffff801bdebfff\n\nProcess name corresponding to current thread: watchdogd\nBoot args: chunklist-security-epoch=0 -chunklist-no-rev2-dev\n\nMac OS version:\n20E241\n\nKernel version:\nDarwin Kernel Version 20.4.0: Thu Apr 22 21:46:47 PDT 2021; root:xnu-7195.101.2~1\/RELEASE_X86_64\nKernel UUID: 068F99A3-1DB3-31C0-87D5-09942F122BB6\nKernelCache slide: 0x0000000018800000\nKernelCache base: 0xffffff8018a00000\nKernel slide: 0x0000000018810000\nKernel text base: 0xffffff8018a10000\n__HIB text base: 0xffffff8018900000\nSystem model name: MacBookPro16,1 (Mac-E1008331FDC96864)\nSystem shutdown begun: NO\nHibernation exit count: 0\n\nSystem uptime in nanoseconds: 3745315881131\nLast Sleep: absolute base_tsc base_nano\n Uptime : 0x000003680639087d\n Sleep : 0x0000000000000000 0x0000000000000000 0x0000000000000000\n Wake : 0x0000000000000000 0x00000003e7e63e5a 0x0000000000000000\nlast started kext at 2652656710011: com.eltima.ElmediaPlayer.kext\t1.0 (addr 0xffffff7fb3bbc000, size 8192)\nlast stopped kext at 269583496430: IOPlatformPluginLegacy\t1.0.0 (addr 0xffffff7fb2104000, size 36864)\nloaded kexts:\ncom.eltima.ElmediaPlayer.kext\t1.0\ncom.parallels.kext.usbconnect\t16.1.3 49160\ncom.parallels.kext.netbridge\t16.1.3 49160\ncom.parallels.kext.vnic\t16.1.3 49160\ncom.parallels.kext.hypervisor\t16.1.3 49160\ncom.intel.driver.EnergyDriver\t3.7.0\n@filesystems.smbfs\t3.5\nAGPM\t122\n!
