Have the same problem, kernel panic regularly happens when I open Alfred, write search query and hit enter. Then everything froze and macos restarts. I've read the topic and understand that Alfred can't cause kernel panic by himself, but maybe it calls some os api that leads to panic. I use MacOS 10.15.1 as well as other and macbook pro 2015. I'll try to change a theme and comeback with updates :) Here is panic log, maybe it could help with future investigation panic(cpu 2 caller 0xffffff800a662e0a): Kernel trap at 0xffffff7f8da5834e, type 6=invalid opcode, registers: CR0: 0x000000008001003b, CR2: 0x0000000118b076b0, CR3: 0x000000000f881000, CR4: 0x00000000001626e0 RAX: 0x0000000000000000, RBX: 0x0000000000000000, RCX: 0x0000000000000000, RDX: 0xffffff9232b23ba0 RSP: 0xffffff9232b23d10, RBP: 0xffffff9232b23d10, RSI: 0x0000000000000503, RDI: 0xffffff802eb30a00 R8: 0x0000000000000000, R9: 0x0000000000989680, R10: 0x0000000000000000, R11: 0x0000000000000003 R12: 0x0000000000000004, R13: 0xffffff802eb12af0, R14: 0xffffff9232b23d30, R15: 0xffffff802eb12af0 RFL: 0x0000000000010286, RIP: 0xffffff7f8da5834e, CS: 0x0000000000000008, SS: 0x0000000000000010 Fault CR2: 0x0000000118b076b0, Error code: 0x0000000000000000, Fault CPU: 0x2, PL: 0, VF: 0 Backtrace (CPU 2), Frame : Return Address 0xffffff9232b23770 : 0xffffff800a539a3b 0xffffff9232b237c0 : 0xffffff800a670fe5 0xffffff9232b23800 : 0xffffff800a662a5e 0xffffff9232b23850 : 0xffffff800a4e0a40 0xffffff9232b23870 : 0xffffff800a539127 0xffffff9232b23970 : 0xffffff800a53950b 0xffffff9232b239c0 : 0xffffff800acd17f9 0xffffff9232b23a30 : 0xffffff800a662e0a 0xffffff9232b23bb0 : 0xffffff800a662b08 0xffffff9232b23c00 : 0xffffff800a4e0a40 0xffffff9232b23c20 : 0xffffff7f8da5834e 0xffffff9232b23d10 : 0xffffff7f8d9b8490 0xffffff9232b23d50 : 0xffffff7f8d9c6655 0xffffff9232b23da0 : 0xffffff7f8d94f6db 0xffffff9232b23e10 : 0xffffff7f8b95d966 0xffffff9232b23e60 : 0xffffff7f8b96b438 0xffffff9232b23ea0 : 0xffffff7f8b96abf8 0xffffff9232b23ee0 : 0xffffff800ac401bd 0xffffff9232b23f30 : 0xffffff800ac3eb02 0xffffff9232b23f70 : 0xffffff800ac3e08c 0xffffff9232b23fa0 : 0xffffff800a4e013e Kernel Extensions in backtrace: com.apple.iokit.IOAcceleratorFamily2(438.2.7)[72B8A0B5-E12C-3764-9187-0AC0E93416F9]@0xffffff7f8b959000->0xffffff7f8ba1cfff dependency: com.apple.driver.AppleMobileFileIntegrity(1.0.5)[180FC5AB-0E47-35BC-91DF-609EBE8ED4A5]@0xffffff7f8b591000 dependency: com.apple.iokit.IOPCIFamily(2.9)[AA7C7A4F-9F5D-3533-9E78-177C3B6A72BF]@0xffffff7f8af2f000 dependency: com.apple.iokit.IOSurface(269.6)[39DC4195-B168-3895-ACD5-E731581855F8]@0xffffff7f8b8c9000 dependency: com.apple.iokit.IOGraphicsFamily(568)[247C211E-C250-351C-BCE2-4DB9D3003E10]@0xffffff7f8b8fa000 dependency: com.apple.iokit.IOReportFamily(47)[2CCA7DD3-C33F-3CA4-A213-BC83D3D997B0]@0xffffff7f8b2c8000 com.apple.kext.AMDRadeonX4000(3.0.2)[1E092428-A3E6-3063-B692-B943B1565B91]@0xffffff7f8d946000->0xffffff7f8dd8bfff dependency: com.apple.iokit.IOPCIFamily(2.9)[AA7C7A4F-9F5D-3533-9E78-177C3B6A72BF]@0xffffff7f8af2f000 dependency: com.apple.iokit.IOSurface(269.6)[39DC4195-B168-3895-ACD5-E731581855F8]@0xffffff7f8b8c9000 dependency: com.apple.iokit.IOGraphicsFamily(568)[247C211E-C250-351C-BCE2-4DB9D3003E10]@0xffffff7f8b8fa000 dependency: com.apple.iokit.IOAcceleratorFamily2(438.2.7)[72B8A0B5-E12C-3764-9187-0AC0E93416F9]@0xffffff7f8b959000 BSD process name corresponding to current thread: kernel_task Mac OS version: 19B88 Kernel version: Darwin Kernel Version 19.0.0: Thu Oct 17 16:17:15 PDT 2019;
